5.  After dropping 5ºF, the temperature was 37ºF.  Which choice models this situation?

• d - 37 = 5
• d + 5 = 37
• d - 5 = 37
• d + 37 = 5

Bill scored 13 points in a basketball game. His teammates (all together) scored x points. The total points for Bill's team was 44 points. What is the variable

• The number of points his teammates scored

• The number of points Bill scored

• The total number of points

Bill scored 13 points in a basketball game. His teammates (all together) scored x points. The total points for Bill's team was 44 points. Write an equation for this situation.

• 44 + 13 = x

• 13 + x = 44

• 44 + x = 13

A cell phone company charges $3.00 to make a phone call plus $0.15 for each minute for each minute you talk. Which equation would you use to determine the total cost, c, of a phone call that is m number of minutes long?

• c = 3.00 - 0.15m
• c = 0.15 + 3.00m
• 3.00 = c + 0.15
• c = 3.00 + 0.15m

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

Mr Carrillo's family bought lunch from Culvers. They also bought some sodas from Quick Trip for $5.00. The meals cost $6.00 each. The total cost of the lunch and soda was $41.00. Let x represent the cost of the number of meals that Mr. Carrillo bought. Write the equation and solve for x.

• -5+6x = 41, 4 meals

• 6x + 5 = 41, 6 meals

• 6x = 36 meals

• 5 + 6x = 41, 7 meals

Scott works on cars. He charges $35 for each car plus $7 per hour. Write an equation that represents this scenario if Kylie's car bill was $63.

• 7x + 35 = 63

• 7x = 63

• 7x + 63 = 35

• 35x + 7 = 63

A car costs $45.00 to rent each day, and an additional $0.25 per mile driven. Which expression represents the cost for renting the car 5 days and driving m number of miles?

• 45 + 0.25m

• 45m + 0.25(5)

• 45(5)m + 0.25

• 45(5) + 0.25m

Jamie baked 48 cookies, which is 8 less than twice the number of cookies Gina baked.

Which equation represents the number of cookies Gina made?
