Question

Kristen works at Best Buy. She receives a base salary of 500 dollars per week plus 4% commission on everything that she sells.

a) create an equation that represents the total earnings in one week. Let x= the total amount of sales.

b) If she wanted to make $720.00 per week how many sales would she have to make per week.

[please explain step by step]

Answer 1

a 500+.04x
The 500 is what they always get no matter what and the .04 is the amount they get for each sale which is represented by x
b 720=500+.04x
Then you let your equation equal the amount you want to make and solve for x by subtracting 500 and dividng by .04
