Company A sells hats for 11 dollars per hat plus a fixed 7 dollars shipping and handling fee. Company B sells hats for 8 dollars per hat plus a fixed 16 dollars shipping and handling fee. The marketing director of company A wants to set up a system of equations to find the number of hats for which the total cost of an order for the two companies is the same. He uses the variables x and y He lets y represent the total cost of an order. What will x represent?
Answer
A
x is equal to total cost of an order
B
x is equal to shipping costs for company A
C
x is equal to shipping costs for company B
D
x is equal to number of hats
Explanation
The total cost depends on the number of hats ordered, so the equations can be written as y = 11x + 7 for Company A and y = 8x + 16 for Company B. Since y represents the total cost, x represents the number of hats. The correct choice is “x is equal to number of hats.”
