Answer:
the numbers are missing here, so I looked for a similar question:
Print-O-Rama
# shirts total cost
10 $95
50 $375
a. Does either pricing model represent a proportional relationship between the quantity of t-shirts and the total cost? Explain.
Value T’s and More offers a proportional relationship since each t-shirt costs $8 regardless of the number of t-shirts
b. What is the constant of proportionality of Value T’s and More? What does it represent?
$8 per t-shirt
f(c) = $8t
the function of total cost = $8 times the number of t-shirts ordered
c. How much is Print-o-Rama’s set-up fee?
using the high-low method
variable cost = ($375 - $95) / /50 - 10) = $7 per t-shirt
fixed cost (set-up fee) = $375 - (50 x $7) = $25
d. If you need to purchase 90 shirts, write a proposal to your teacher indicating which company the team should use. Be sure to support your choice. Determine the number of shirts that you need for your team.
purchasing 90 t-shirts at Print-o-Rama costs = $25 + (90 x $7) = $655
purchasing 90 t-shirts at Value T’s and More costs = 90 x $8 = $720
you should purchase the t-shirts at Print-o-Rama since the cost is lower.
