Hint 2 of 2
Take away the 7 Kangas she paid; match what is left to a picture.
Show solution
Approach: total the money, then subtract the price
- The purse holds a 10, two 2-coins and a 1-coin: 10 + 2 + 2 + 1 = 15 Kangas.
- Paying 7 for the ball leaves 15 − 7 = 8 Kangas.
- The purse that adds up to 8 is the 5 + 2 + 1 picture.
- That is option B.
