Question

Can you please help me and I have more questions

Answer 1

As given that P as profit and m as amount of money and h as hours:

`P=m-(250+4h)`

The equation to calculate the amount of money m when profit is $415:

Put the the value of P as 415 in given equation:

`\begin{gathered} 415=m-(250+4h) \\ 415=m-250-4h \\ 415+250+4h=m \\ m=665+4h \end{gathered}`

So the desired equation for calculate amount of money m is:

`m=665+4h`
