6.3 Writing two-step equations

Speedy Boat Rental charges a $15 deposit fee plus $2 for each hour of use to rent a paddle boat.  Write an equation to find out how many hours, h, they rented the Boat if the total cost was $33.

• h = 2(9) + 15

• 33 = 15h + 2

• h = 15(9) + 2

• 33 = 2h + 15

9 increased by m is 15

• m + 15 = 9

• 9  + m = 15

• 9 x m = 15

• 9 + 15 = m

Twice a number plus 6 is -72

• 2 + 6x =- 72

• 2x + 6 = -72

• 2 + 6 = x

• 2x² + 6 = 72

Eight less than 7 times a number is the same as 4 more than 3 times the number

• x + 3 = x

• 8 = x + 4 + 3

• 8 - 7x = 4 + 3x

• 7x - 8 = 3x + 4

Pizzazz Publications is having some books printed. The printer charges $800 plus $5 per book. What equation could help me find how many books can be printed for $4,000?

• 800 + 5x = 4000

• 800x + 5 = 4000

• 4000 + 5x= 800

• 800 + 5 = 4000

Which equation matches the following situation? 331 students went on a field trip. Six buses were filled and 7 students traveled in cars. How many students were in each bus?

• n= # of students in each bus; 6n + 7 =331

• n=# of buses; 6n + 7 =331

• n= # of students in each bus; 6 + 7n =331

• n= # of students in each bus; 6n - 7 =331

WRITE AN EQUATION
April had $24 to spend on seven pencils. After buying them she had $10. How much did each pencil cost?

• n=total cost pencils; 7n+10=24

• n=cost of 1 pencil; 7n-10=24

• n=cost of 1 pencil; 7n+10=24

• n=cost of 1 pencil; -7n-10=24

You bought a magazine for $5 and four erasers. You spent a total of $25. How much did each eraser cost?  (Define 'n' and write the equation.) 

• n=total cost of erasers; 5 + 4n = 25

• n=cost of 1 eraser; 5 - 4n = 25

• n=cost of 1 eraser; 5n + 4 = 25

• n=cost of 1 eraser; 5 + 4n = 25
