Step-by-step explanation:
Length or ribbon = Circumference of the circle
C = 2πr
C = 2π(3.5)
C = 21.99
Alex bought all the string needed for $125.
It costs $18 for the remaining materials to make each puppet.
So if we closely observe then we see that here $125 is the fixed cost because its not going to change with number of puppets.
And the variable cost is $18.
In this case we can model a Total cost function C(x) for for x number of puppets as below

The total cost to make 50 puppets=$1025
Answer:
Height 4 ft
Step-by-step explanation:
Surface area= 2(lw + lh + wh) =
2(16)16)+2(16h)+2(6h) =
2(16)(6)+32h+12h=368
192 + 44h = 368
44h = 368 - 192
44h = 176
h = 176/44
