Question

Please answer fast 1. Each week, Bart earns a base rate of $85 and a commission on each dollar of merchandise he sells. If Bart sells $3600 in one week and c represents the commission percentage, which algebraic expression represents his earnings for that week?
2.A rental car agency charges a base fee of $60.00 plus $0.25 per mile travelled. Which algebraic expression represents the cost of renting a car from the agency after traveling m miles?

Answer 1

85 + 3600c

and : c(cost)=60.00 + 0.25m(miles)

Answer 2

1. It depends on the form of "c". If we realize that a commission percentage of 10% is identical in value to 0.10, then we can compute the commission as 3600c. If the commission percentage of 7% is given as c=7, then we need to compute the commission as 3600·(c/100) = 36c. We will assume the former.

... (Bart's earnings) = 85 + 3600c

2. The cost of a rental is the base fee plus the mileage charge multiplied by the number of miles:

... (cost of renting) = 60.00 + 0.25m
