can anyone help me

Answer 1

#35 "A person hired a firm to build a CB radio tower. The firm charges $100 for labor for 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?"

Answer 2

for every 10 feet of tower, the change in price is $25

Answer 3

see if you can model that as a linear equation.
