Question 1192244: Katie went to the driving range to hit some golf balls. While she was there, she decided to take a 30-minute lesson. The table shows how the total cost of the practice session depends on the number of buckets of golf balls Katie hits. What is a rule for the total cost of the practice session? Give the rule in words and as an algebraic expression.
Table:
Number of Buckets | Total Cost
2 | (5 x 2) + 40
4 | (5 x 4) + 40
6 | (5 x 6) + 40

let the number of buckets be x
fixed upfront cost is 40
5+is the cost of each bucket
rule: 5 times the number of buckets plus 40

5x%2B40
