Question

You’re assisting a craft vendor at a fair who sells 5 knit hats for $9.50 each. She then sells the sixth and seventh for $11.25 each, and the eighth and ninth for $8.75 each. At the end of the fair, she is charged 15% of her gross earnings for the booth space. How much money does she make after paying for the booth space?

Answer 1

She earned a total of:

`5(9.50)+2(11.25)+2(8.75)=\$ 87.50`

If she pays 15% for the booth space, she keeps 85%.

`87.50(0.85) \approx \boxed{\$ 74.38}`
