Answer:
Step-by-step explanation:
A)
(22+12)/2 = [17] (12+17)/2 = [14.5] (17+14.5)/2 = [15.75]
B)
(10.5*2) - 5 = [16] ......... NOT 13
55x + 10 = 57x....where x = number of months
10 = 57x - 55x
10 = 2x
10/2 = x
5 = x.....they will cost the same at 5 months...they will each cost $ 285 at 5 months
Answer:
