Question

The total cost f(x), in dollars, for renting a houseboat for x days is shown:

f(x) = 15 + 150x

What does f(15) represent?

A.The number of dollars it costs for 15 people to rent the houseboat

B.The number of houseboats that can be rented for 15 days

C.The number of dollars it costs to rent the houseboat for 15 days.

D.The number of days the houseboat can be rented for a cost of $150​

Answer 1

Answer: Option 'c' is correct.

Explanation:

Since we have given that

f(x) = 15+150x

Here, x represents the number of days,

f(x) represents the total cost.

If we calculate f(15), we get that

`f(15)=15+150* 15\\\\f(15)=15+2250\\\\f(15)=2265`

$2265 is the cost for 15 days.

So, it shows the number of dollars it costs to rent the houseboat for 15 days.

Hence, Option 'c' is correct.

Answer 2

C.The number of dollars it costs to rent the houseboat

for 15 days.

Explanation:

f(x) - total cost in dollars, for renting a houseboat for x days.

f(15) → x = 15 - number of days

f(x) = 15 + 150x → f(15) = 15 + 150(15) = 2,265 - total cost in dollars for 15 days
