Question

Eric and his wife are each starting a saving plan. Eric will initially set aside $50 and then add $30.65 every week to the savings. The amount A (in dollars) saved this way is given by the function A=50+30.65N, where N is the number of weeks he has been saving.

His wife will not set an initial amount aside but will add $55.85 to the savings every week. The amount B (in dollars) saved using this plan is given by the function B= 55.85N.
Let T be the total amount in dollars saved using both plans combined. Write and equation relation T to N. Simplify your answer as much as possible

Answer 1

T=50+86.49N

Explanation:

you just have to combine A and B.

Total (T)=A(50+30.65N)+B(55.85N) thank just open the prentices and add 30.65N and 55.85N=86.49N. so total is initial savings+ weekly savings by both.
