A) The cost of playing n games of bowling is C(n) = $7.50 + (n - 1) . $2.50
Step-by-step explanation:
The cost of first game of bowling for each person = $7.50
Cost after first game per person = $2.50
Total number of games played = n
According to the question:
Total cost of playing n games = Cost of first game + {(n-1) x Cost after first game}
or, C(n) = $7.50 + (n-1)$2.50
Hence, the cost of playing n games of bowling is
C(n) = $7.50 + (n - 1) . $2.50
