C.
D.
To find : Which equation represents how many chimes are needed to sell in a week to meet the goal?
- 12c -625=3500
- 5(12c )-125=3500
- 5(12c+ 125)=3500
- 5(12c -125)=3500
Answer to Problem 5STP
A. 12c -625=3500
Explanation of Solution
Given information: A merchant is selling wind chimes from a booth at a flea market. He rents his space for $125 per day. The profit from each wind chime sold is $12. His goal is to make $3500 in a five day work week.
Calculation:
Let c be the number of wind chimes sold in a week to meet the goal.
Profit from each wind chime sold = $12
Then profit from c wind chime sold = $(12c )
Fixed rent for space per day =$125
Therefore, fixed rent for a five day work week =$625
Total money earned in a week = $ (12c -625)
Now, to meet the goal, we have
12c -625=3500
The equation that represents the number of chimes that are needed to sell in a week to meet the goal is
12c -625=3500
