Question

Justin and his wife are each starting a saving plan. Justin will initially set aside $75 and then add $20.55 every week to the savings. The amount A (in dollars) saved this way is given by the function A=20.55N+75, where N is the number of weeks he has been saving.
His wife will not set an initial amount aside but will add $60.75 to the savings every week. The amount B(in dollars) saved using this plan is given by the function B=60.75N
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.

Answer 1

Just set T=sum of both plans.

Answer 2

I dont understand... @Kinged

Answer 3

A gives the amount saved by justin while B gives the amount saved by his wife. then the total amount saved by both of them is A + B. Question tells u that this sum is named T.

Answer 4

@princesssleelee

Answer 5

95.55+60.75=156.30

Answer 6

@HollowDensity

Answer 7

@princesssleelee nope, A and B are not the values but the equations

Answer 8

u need to relate T to N in some equation

Answer 9

@princesssleelee T = A + B, replace in the equations for A & B

Answer 10

im completely lost

Answer 11

156.30N

Answer 12

to get rid of A & B, and u will be left with the equation that only have T and N

Answer 13

20.55N + 75 + 60.75N

Answer 14

156.30(N)

Answer 15

add the coefficients of terms that have the same base to simplify

Answer 16

81.30N+75

Answer 17

yea

Answer 18

What would i do from there

Answer 19

T = 81.30N + 75 is the solution

Answer 20

do i simplify by adding in the 75?

Answer 21

making it 156.30N

Answer 22

so nothing. read ur questions carefully to know what they require as answer

Answer 23

those two terms can not be added because they do not have the same base.

Answer 24

T = 81.30N + 75 is the answer. it is the equation that relates T to N

Answer 25

N is number of days and T is total savings by the two of them in N peroid

Answer 26

sorry N is the number of weeks

Answer 27

Tthank you

Answer 28

any time. read questions carefully before starting to solve. To know what is given and what must u find
