Question

Specialty t-shirts are being sold online for $25 plus a one-time handling fee of 275. The total cost is a function of the number of tshirts bought. What function rule models the cost of the t-shirts? Evaluate the function for 8 tshirts

Answer 1

Answer: $475. The cost of the t-shirts can be modeled using the function rule Cost(x) = 25x + 275. Evaluating the function for 8 t-shirts gives a cost of $475.

Step-by-step explanation:

Using a function rule, the price of the specialized t-shirts may be estimated. Let us denote the quantity of t-shirts purchased as 'x'. The handling fee plus the cost of the t-shirts add up to the total cost. The handling fee is $275 and the cost of the t-shirts is 25 times the quantity of t-shirts purchased (25x). For the total cost, the function rule is as follows:

Cost(x) = 25x + 275

To evaluate the function for 8 t-shirts, we substitute x = 8 into the function:

Cost(8) = 25(8) + 275 = 200 + 275 = 475

So the cost of 8 t-shirts is $475.

Answer 2

f(s) = 25s + 275

f(8) = (25)(8) + 275 = $200 + $275

= $475
