Question

A insurance salesperson earns a salary of $4,200 per month plus a commission of 3% of sales. How much must the salesperson have to sell to make an income of at least $4,500?

Answer 1

x = 10,000

Explanation:

commision earned = $4500. - $4200

commision = 300

therefore:

commision = 3% of the amount of the sales

300 = 3% of x( the price isn't known)

300 = 3/100 * x

300 = 3x /100

multiplying both sides by 100

300 x 100 = 3x/100 x 100

30000 = 3x

Divide through by 3

x = 10,000.

the amount of the sales = 10,000

______________

To check

commision = 3% of 10,000

commision = 300
