Question

Kat sells T-shirts at concerts. She is paid $25 per concert and 50¢ for each T-shirt she sells. Kat must pay 10% in taxes. What was Kat’s net income for selling 174 T-shirts at one concert?

Answer 1

Per concert: $25

Per T-shirt: 50¢ = $0.50

If she sold 174 T-shirts at one concert, then:

$\ 25+174\cdot\ 0.50=\ 25+\ 87=\ 112$

Finally, knowing that Kat must pay 10% in taxes, her net income is:

$\frac{90}{100}\cdot\ 112=\ 100.80$
