Question

For a school fundraiser, Elena will make T-shirts. She will order T-shirts and print graphics on them. Elena must spend $349 on a printing machine and $4.80 per shirt for the blank shirts, ink, and other supplies. How much does it cost to make 40 shirts?

Answer 1

Hi, to answer this question we have to analyze the information given:
Printing machine cost: $349
Cost per shirt: $4.80
a)
Number of T-shirts : 20
To find the cost we have to multiply the cost of each t-shirt by the number of t-shirts, and add the cost of the machine.
cost: $349 + (20x $4.80) = $445
number of T-shirts : 40
cost : $349 + (40x $4.80) = $541
number of T-shirts : 60
cost : $349 + (60x $4.80) = $637
b) y = 349 + n (4.80)
where:
y= total cost in dollars
n = number of T-shirts
