Answer:
X = 9 months
Step-by-step explanation:
To solve the number of months when the cost of each payment
are the same, you should equate the two cost. First establish the equations
Let A be the cost of first payment method
B is the cost of the second payment method
X is the number of months
A = 38x + 15
B = 31x + 78
38x + 15 = 31x + 78
7x = 63
X = 9 months
C - 0.15c is the same as 1c - 0.15c.
1 - 0.15 = 0.85.
Joe can also use 0.85c.
Area of a circle = PI x r^2
Area = 3.14 x 11^2
Area = 3.14 x 121
Area = 379.94 square cm.
