Specialty t-shirts are being sold online for $30 for each plus a one time handling fee of $2.75. The total cost is a function of the number of t-shirts bougt. WHat function rule models the cost of the t-shirt? evaluate the functon for 5 tshirts
The function rule that models the cost of the t-shirts is:
C(x) = (30x) + 2.75
Where:
C(x) represents the total cost of x t-shirts
To evaluate the function for 5 t-shirts, we substitute x = 5 into the function:
C(5) = (30(5)) + 2.75
C(5) = 150 + 2.75
C(5) = 152.75
Therefore, the cost of 5 t-shirts would be $152.75.
The cost of the t-shirts can be modeled using the following function rule:
Cost = (Price per t-shirt * Number of t-shirts) + Handling fee
In this case, the price per t-shirt is $30 and the handling fee is $2.75. Thus, the function rule for modeling the cost of the t-shirts is:
Cost = (30 * x) + 2.75
To evaluate the function for 5 t-shirts, simply replace "x" with 5 in the function:
Cost = (30 * 5) + 2.75
= 150 + 2.75
= $152.75
Therefore, the cost of 5 t-shirts would be $152.75.
To determine the function rule that models the cost of the t-shirt, we need to consider the fixed handling fee of $2.75 and the variable cost of each t-shirt, which is $30.
Let's define "x" as the number of t-shirts bought.
The cost of x t-shirts can be obtained by multiplying the cost of each t-shirt ($30) by the number of t-shirts (x), and then adding the one-time handling fee ($2.75). So, the function rule that models the cost is:
Cost(x) = (30 * x) + 2.75
To evaluate the function for 5 t-shirts, we substitute x = 5 in the function:
Cost(5) = (30 * 5) + 2.75
Cost(5) = 150 + 2.75
Cost(5) = $152.75
Therefore, the cost of 5 t-shirts is $152.75.
