Question

Justin and his wife are each starting a saving planJustin will initially set aside 750 and then add $145 every month to the savings. The amount in dollars) saved this way is given by the function A = 145N + 750 where N is the number of months he has been saving wife will not set an initial amount but will add to the savings every month. The amount B (in dollars) saved using this plan is given by the function B - 48SN Let be total amount (in ) saved using both plans combinedWrite an equation relating to N. Simplify your answer as much as possible

Answer 1

Explanation

We are given the following:

`\begin{gathered} A=145N+750 \\ B=485N \end{gathered}`

We are required to determine the total amount (P) saved using both plans combined.

This can be achieved thus:

`\begin{gathered} T=A+B \\ T=(145N+750)+(485N) \\ T=145N+750+485N \\ T=145N+485N+750 \\ T=630N+750 \\ T=30(21N+25) \end{gathered}`

Hence, the answer is:

`T=30(21N+25)`
