A = 70*M
B = 500 + 50*M
Costing the same means equal, so we have the equation:
70M = 500 + 50M
-50M -50M
20M = 500
20M / 20 = 500 / 20
m- 25 months
Answer:
Simplifying
12t + -8t = 0
Combine like terms: 12t + -8t = 4t
4t = 0
Solving
4t = 0
Solving for variable 't'.
Move all terms containing t to the left, all other terms to the right.
Divide each side by '4'.
t = 0
Simplifying
t = 0
