The School Fun Run
1 / 7The school Fun Run is this weekend! Two friends, Ava and Ben, are in charge of fundraising for new gym equipment. They each run a different booth.
🎟️
Ava
Ava runs the main booth, selling entry passes for $5 each and snack packs for $2 each.
At the end of the day, she sold 30 items total and collected $108.
How many of each did she sell?
👕
Ben
Ben runs the T-shirt table, selling small shirts for $8 and large shirts for $12.
He sold 25 shirts total and collected $244.
How many of each size did he sell?
Both have two unknowns and two clues. Can we figure out the exact answer — and what's the fastest way to do it?
