Algebra practice question
Mia paid $14 in total for a $2 bag of ice and some bottles of water that cost $3 each. How many bottles of water did she buy?
Answer: 4
2 + 3b = 14 gives 3b = 12, so b = 4.
Common wrong answers
- If you answered 3
- 3 is the price of one bottle.
- If you answered 5
- 5 comes from 14 ÷ 3 rounded, ignoring the bag of ice.
- If you answered 12
- 12 is the money spent on water, not the number of bottles.
