Abigail has $72 to spend on prizes for bingo. She plans to buy individual slime kits that cost $6 each and yo yo's that cost $3 each.

If x represents the number of individual slime kits that Abigail buys and y represents the number of yo yo's that Abigail buys, then which equations represent this situation?
Choose 2.
a: 3x + 6y = 72
b: 2x + y = 24
c: y = 2x + 24
d: y = -1/2x + 24
e: y = -1/2x + 12
f: y = -2x + 24

The two equations that represent this situation are:

a: 3x + 6y = 72
b: 2x + y = 24
