Respuesta :

Let G be the cost os monthly game subscriptions, P the cost of a wekly phone bill, D = $30 the cost of a package of 42 diapers, F the cost of pizza on fridays and W the amount she receives each workday.

Then, for a initial amount I = $100, the money M she still have after the events in the text is given by:

[tex]\begin{gathered} M=(W+I)-(G+P+D+F) \\ M=(W+100)-(G+P+30+F) \\ M=W+70-G-P-F \end{gathered}[/tex]

If F + G = $65 and P = $150, we have:

[tex]\begin{gathered} M=W+70-65-150 \\ M=W-145 \end{gathered}[/tex]

If we are considering only how much she payed for the diapers and the phone bill, we have:

[tex]D+P=30+150=\text{ \$}180[/tex]
