Question

Let T be total amount (in dollars) saved using both plans combined. Write an equation relating T to N. Simplify your answer as much as possible.Hong and his wife are each starting a saving plan. Hong will initially set aside $250 and then add \$155 every month to the savings. The amount A (in dollars) saved this way is given by the function A=155N-25O, where N is the number of months he has been saving His wife will not set an initial amount aside but will add $385 to the savings every month. The amount B (in dollars) saved using this plan is given by the function B = 385N

Answer 1

Answer:

T = 540N + 250

Explanation:

The amount saved by Hong after N months is

A = 155N + 250

And the amount saved by his wife after N months is

B = 385N

Then, the total amount saved is the sum of these expressions, so

T = A + B

T = (155N + 250) + (385N)

Simplifying, we get

T = 155N + 250 + 385N

T = 540N + 250

Therefore, the answer is

T = 540N + 250
