Answer:
5a. A = 800 +150m
5b. A = 200 +200m
6. 12 months
Step-by-step explanation:
<h3>5.</h3>The amount repaid will be the sum of the deposit and the total of monthly payments. That total is the number of months times the payment amount.
Equation 1: A = 800 +150m
Equation 2: A = 200 +200m
__
<h3>6. </h3>The lines on a graph cross at m = 12. It will take 12 months for the amount repaid to be the same for both plans.
__
Subtracting the second equation from the first gives ...
(A) -(A) = (800 +150m) -(200 +200m)
0 = 600 -50m . . . simplify
50m = 600 . . . . . add 50m
m = 600/50 = 12
Note that this answer is the quotient of the difference in deposits and the difference in payment amounts.
