Suppose a car rental company charges $94 for the first day and $44 for each additional or partial day. Let S (x) represent the cost of renting a car for x days. Find the value of S (3.5).

S (3.5) = $204

Explanation:

The car rental company charges $94 for the first day. $44 for each additional day or partial day. Using S (x) to represent the cost of renting a car for x days, the formula can be computed as follows

S (x) = 94 + 44 (x)

where x = 3.5 days

it means the first day + 2 additional day + 1 partial day

The first day rental cost = $94

Each additional day or partial day = $44

Cost for 2.5 days = 2.5 * 44 = $110

S (3.5) = 94 + 44 (2.5)

S (3.5) = 94 + 110

S (3.5) = $204
