Question

you have saved $103.25 and will be working at trump the trumpet music store for $11.35/hr. How many hours must you work to buy your first car of $2550.99?

Answer 1

Since you have already saved $103.25, substract that amount from the total cost of the car to find the remaining amount of money that you have to earn:

`2550.99-103.25=2447.74`

Let h be the amount of hours that you need to work to earn 2447.74. Since you are paid $11.35 for each hour, after h hours you would have won:

`11.35h`

For you to be able to buy that car, that amount must be equal to $2447.74:

`11.35h=2447.74`

Divide both sides by 11.35 to isolate h:

`\begin{gathered} h=(2447.74)/(11.35) \\ \Rightarrow h=215.6599\ldots \end{gathered}`

Therefore, you must work for approximately 215.66 hours to buy your fist car of $2550.99
