Question

Evaluate an expression for how much money Maria would earn in one day

Answer 1

`\begin{gathered} T=10.75+7.10h-5.50 \\ T=7.10h+5.25 \end{gathered}`

where h is the number of hours and T the total earn on 1 day

now we transform the mixed number on a fraction to repalce easlier

`4(1)/(2)\longrightarrow((2*4)+1)/(2)=(9)/(2)`

now replace h=9/2

`\begin{gathered} T=7.10h+5.25 \\ T=7.10((9)/(2))+5.25 \\ T=31.95+5.25 \\ T=37.2 \end{gathered}`

Marie earn $37.2 in one day if she worked for 4 1/2 hours
