Miguel and his wife are each starting a saving plan.

Miguel will initially set aside $75 and then add $30.65 every week to the savings. The amount A (in dollars) saved this way is given by the function A= 75+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 total amount (in dollars) saved using both plans combined.

Write an equation relating to N. Simplify you answer as much as possible.

anonymous · Answer

T = N ((75 + 30.65) + (55.85))

anonymous · Answer

I wasn't quite sure where to start so I'm not sure if i'm on the right track or not =o @amistre64

anonymous · Answer

T= N (105.65) + (55.85)
T= N (161.5)

anonymous · Answer

OR is it T = N((30.65) + (55.85)) + 75 ( since 75$ deposit was only made once)
T = 86.05N + 75

amistre64 · Answer

A + B

you cant factor our an N from 75 since it has no N to start with

amistre64 · Answer

75 + 0 is the initial amount thats not changeing

31 + 56 is added each N, so this amount changes the value in the account over time.
