A restaurant wants to buy paper plates in bulk so they want to join a

wholesale store. There are two stores they could join:
Store 1: Charges a membership fee of $100 and charges $25 per bulk
package of paper plates.
Store 2: Charges a membership fee of $50 and charges $30 per bulk
package of paper plates.
Which store would give the overall cheapest price if the restaurant
needed to buy five packages of paper plates?
What is the cost at that store?
$

Answer 1

store 2

Explanation:

store 1 charges 225

(25*5) +100

125+100=225

store 2 charges 200

(30*5)+50

150+50=200

Answer 2

Store 2

Explanation:

Drawing graphs will help you understand better

S1

y = 25x + 100

S2

y = 30x + 50

Where y is the total cost that needs to be paid

And x is the number of packages

Store 1

y = 25(5) + 100

y = 125 + 100

y = 225

Store 2

y = 30(5) + 50

y = 150 + 50

y = 200
