Question

Is $12 enough to buy a half gallon of milk for $2.30, a bag of apples for $3.99, and four cups of yogurt that cost $0.79 each? Explain.

Answer 1

1.how much are all the yogurts? since .79×4 is 3.16, that's how much they cost

2. figure out the total cost. we must add the 3 prices together:
2.3+3.99+3.16
9.45

3.since you have $12 and the total is only $9.45, you do have enough with $2.55 left over! :)
