the first 10 feet. After that, the cost of the labor for each succeeding 10 feet is $25

more than the preceding 10 feet. That is, the next 10 feet will cost $125, the next

10 feet will cost $150, etc. How much will it cost to build a 90-foot tower?

looks like an arithmetic series to me

a = 100

d = 25

n = 9

apply the sum formula
