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:

`(90)/(100)\cdot\$112=\$100.80`
