Week 19: Lesson 2

Week 19: Lesson 2

ALL students will do this lesson on WEDNESDAY

This lesson must be turned in before midnight on Sunday, January 24th to receive full credit.

Multiple Choice

#1) Mr. Gollow bought triple as many pencils as Ms. Boggs. If Ms. Boggs purchased p pencils, then how many pencils did Mr. Gollow purchase?

• p/3

• p + 3

• p - 3

• 3p

Triple means three times as many, so we need to multiply the number of pencil Ms. Boggs has by 3 to find out how many Mr. Gollow had. If Ms. Boggs is p, the expression will be: 3p

(remember, no X for multiplying!)

Multiple Choice

#2) Students brought in 300 canned goods for the food drive on Monday. On Tuesday students brought in x more than the day before. Write an expression for how many canned goods students brought on Tuesday.

• x + 300

• 300 - x

• 300x

• x - 300

"More" means addition

"Than" reverses the order

The correct expression would be

x + 300

Multiple Choice

#3) Mary baked some cookies on Saturday. On Sunday she baked twice as many cookies as the day before. If c represents the number of cookies she made on Saturday, write an expression for the number of cookies she made on Sunday.

• c + 2

• c - 2

• c / 2

• 2c

"twice as many" means you need to multiply by 2

the expression will be 2c

(remember, we don't use X to show multiplication in algebra)

Multiple Choice

#4) Pam put pink frosting on one-fourth of the cookies she made. If y is the total number of cookies she made, which expression shows the number of cookies with pink frosting?

• ¼ y

• ¼ + y

• y - ¼

• y ÷ ¼

To find out what one-fourth of a whole number is, you would divide by 4. In this situation, the whole number of cookies is represented by y. The correct expression would be: y/4

(remember, we use the fraction bar to show division in algebra)

Multiple Choice

#5) Oscar bought n ride tickets at the carnival. Esther bought 4 times as many ride tickets as Oscar. Which expression represents the total number of ride tickets that Oscar and Esther bought?

• $4n\ +\ 4n$

• $n\ +\ 4n$

• $n\ +\ 4$

• $4n$

Since Esther bought 4 times as many tickets at Oscar, we would multiply Oscar's amount by 4 to find out how many Esther bought: 4n

The problem wants an expression for how many Oscar and Esther bought combined, so you need to add their amounts together: n + 4n

Multiple Choice

#6) Marion is 3 years more than 5 times as old as Paula. If p represents Paula’s age, which expression represents Marion’s age?

• 3p + 5

• 3p - 5

• 5p + 3

• 5p - 3

"5 times as old as Paula" means 5p

"3 years more than" means addition, but reverse the order for "than"

The correct expression would be:

5p + 3

Multiple Choice

#7) Hilary bought a jacket that cost $10 more than double the price of the sweater she bought. The price of the sweater was s dollars. What was the cost of both items?

• $2s\ +\ 10\ +\ s$

• $2s\ +\ 10\ -\ s$

• $10s\ +\ 2\ +\ s$

• $10s\ +\ 2\ -\ s$

"$10 more than" means you will add 10 add the end of the expression (than reverses the order)

"double the price" means multiply by 2

The correct expression would be:

2s + 10

to show 2 times the price of the sweater (s) plus the extra $10

Multiple Choice

#8) Mrs. Bembry puts $10 in a savings account each month and an extra $20 when she receives money for her birthday. If her birthday was this week, which expression represents the amount she has saved this year?

• 20m + 10

• 20m - 10

• 10m - 20

• 10m + 20

If she saves $10 each month, you will write that as 10m (the amount of money times the number of months).

You will need to add the extra birthday money at the end.

The correct expression will be: 10m + 20

Multiple Choice

#9) Jacob collects hats. He has 6 hats already, and he collects 2 hats a week (w). Which expression can you use to find out how many hats he will have collected at any point in a year (y)?

• y = 6 + 2w

• y = 6w + 2

• y = 2w - 6

• y = 6w - 2

Start with 6 hats.

Then add the expression for 2 hats a week times an unknown number of weeks: 2w

The expression will be: 6 + 2w

Multiple Choice

#10) If chocolate chip cookies cost $3.00 per cookie (c) plus $2 for boxing them up in a decorated box, what would the expression be?

• 3 + 2c

• 3c + 2

• 3c + 2c

• 5c

You will multiply the cost of each cookie by how many cookies you buy: 3c

You then need to add the $2 boxing fee: +2

The complete expression will be: 3c + 2

THE END!!!
