Ursula is making treasure boxes for campers. There are 12 younger campers, and each of their boxes contains 4 prizes. There are 10 older campers, and each of their boxes contains 6 prizes. Drag the tiles to complete an expression to represent how many prizes Ursula needs in all. Tiles may be used once, more than once, or not at all.
+ x 4 6 10 12
(12× ) (10× )
(12×4) + (10×6) = 48 + 60 = 108
So Ursula needs 108 prizes in all.
