Answer:
x=6
Step-by-step explanation:
6x-x=5x
33-3=30
30/5=6
x=6
R = - 4
t1 = 6
tn = a1*r^(n - 1)
t6 = 6 * (-4)^(6 - 1)
t6 = 6 * (-4)^5
t6 = 6 * (-1024)
t6 = -6144
A) Garage A = 3x
Garage B = 2x + 2
b) 2x + 2 = 3x
x = 2
c) the solution, 2, means the number of hour which both garages would have the equal amount of cost. In this case, in 2 hours, they would be equal in cost.
