Question 2 Christine and her husband are each starting a saving plan. Christine will initially set $50 aside and then add $50.85 every week to the savings. The amount A (in dollars) saved this way is given by the function A=50+50.85N, where N is the number of weeks she has been saving. Her husband will not set an initial amount aside but will add to the savings every week. The amount (in dollars) saved using this plan is given by the function. 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: N=0.019666a-0.983284 or

A=50.85n+50

Step-by-step explanation:

Let's solve for n.

a=50+50.85n

Step 1: Flip the equation.

50.85n+50=a

Step 2: Add - 50 to both sides.

50.85n+50+-50=a+-50

50.85n=a-50

Step 3: Divide both sides by 50.85.

50.85n

50.85

=

a-50

50.85

n=0.019666a-0.983284

Let's solve for a.

a=50+50.85n
