Question

Sarah wants to take a vacation that will cost 2,562 if sarah plans to save for 9 months, then how much needs to be saved per month

Answer 1

Let:

x = Number of months

y = Total savings

a = Savings per month

so:

`\begin{gathered} y=ax \\ where \\ y=2562 \\ x=9 \\ so\colon \\ 2562=9a \\ solve_{\text{ }}for_{\text{ }}a\colon \\ a=(2562)/(9) \\ a\approx284.67 \end{gathered}`

She needs to save approximately $284.67 per month
