Felix earns $450 per week plus 3% of sales over $4800. Felix’s sales are $53000. How much does Felix earn?

Leni [432]

1. Felix’s sales are $53000. He has 3% of sales over $4800, then he has 3% of sales $(53000-4800)=$48200.

Now

$48200 -- 100%

$x -- 3%.

Write a proportion:

$\dfrac{48200}{x}=\dfrac{100}{3},\\ \\x=\dfrac{48200\cdot 3}{100}=482\cdot 3=1446.$

Thus, he additionally gets $1446.

2. If he earns $450 per week and earns $1446 of sales, then Felix earns

$450+$1446=$1896.
