Evan earns $9.45 each hour he works. How much did he earn last week if he worked 18 hours? Can anyone answer this???
We can use dimensional analysis: Therefore, we have \(18h*\frac{9.45}{h}=18*9.45=\boxed{170.1}\) .
.....using dimensional analysis 18hr * $ 9.45 / hr = $ 170 .10 (don't forget units )
