A sporting goods store is selling x gym bags and y backpacks. • The price of each gym bag is $26.
• The price of each backpack is $48.
• The total cost to buy all the gym bags and backpacks is $2,220.
• The store has 60 gym bags and backpacks in all.
Which two equations could represent this situation?
A.
48x + 26y = 2,220
x + y = 60
O B.
48x + 26y = 60
x + y = 2,220
O C.
26x + 48y = 60
x + y = 2,220
OD.
26x + 48y = 2,220
x + y = 60
