A driving range charges $4 to rent a golf club plus $2.75 for every bucket of golf balls you hit. Write an equation that shows the total cost c of hitting b buckets of golf balls.

The correct answer is: c = 2.75b + 4

GIVEN-
rent of golf ball = $ 4
Cost of 1 golf ball bucket = $ 2.75 per bucket.
TO FIND-
Equation for the given situation to determine the total cost 'c' when 'b' buckets of balls are hit.
SOLUTION-
We know that-
Cost of golf balls = Number of buckets of balls bought * rate per bucket
∴ Cost of golf balls = b * $ 2.75 …....................................................................... (From given information)
∴ Cost of golf balls = 2.75b ............................................................................... (Equation i)
Total cost = rent of golf club + cost of golf balls
∴ c = 4 + 2.75b ............................................................................ (From Equation i & given information)
FINAL ANSWER-
Option 'a' i.e. 'c = 4 + 2.75b' is the correct answer to the given question.
