Specialty t-shirts are being sold online for $30 plus a one-time handling fee of $2.75. The total cost is a function of the number of t-shirts bought. What function rule models the cost of the t-shirts? Evaluate the function for 5 t-shirts.
1 A Domain (-4,-1,1,4) range (-1,1,4) yes this is a relative function
2 D 30t+2.75=152.75
3 C 327.6
4 A 5
5 B y=2/7(x)-12
6 C
7 C y-15=-3(x+2)
8 D y+8=3(x-8)
9 A 17x+10y=85
10 D X(3,0) Y(0,5)
11 C y=9/5x+32
12 C y=-9/4 x+12
i hate the name but they're right :/ ^^^
not like your name is any better
a. C = 30x + 2.75.
b. C = 30*5 + 2.75 = $152.75.
To determine the function rule that models the cost of the t-shirts, we need to consider the fixed cost for each shirt and the variable cost based on the number of t-shirts bought.
Let's break it down step by step:
1. The fixed cost for each t-shirt is $30.
2. In addition to the fixed cost, there is a one-time handling fee of $2.75.
To find the total cost for a given number of t-shirts, we need to multiply the fixed cost by the number of t-shirts and add the handling fee.
The function rule, in this case, can be represented as:
C(x) = (Fixed cost per t-shirt) * (Number of t-shirts) + Handling fee
C(x) = 30x + 2.75
Now, to evaluate the function for 5 t-shirts, we substitute 5 for x:
C(5) = 30(5) + 2.75
C(5) = 150 + 2.75
C(5) = 152.75
Therefore, the cost of 5 t-shirts is $152.75.
