Ben had $35.40 less than Zara. He spent
23 of his money on a marker which cost $2.80. Zara spent
14 of her money on a jumpsuit. How much had Zara left?
| |
Ben |
Zara |
| Before |
3 u |
4 p |
| Change |
- 2 u |
- 1 p |
| After |
1 u |
3 p |
Amount that Ben spent on the marker = 2 u
2 u = 2.80
1 u = 2.80 ÷ 2 = 1.40
Amount that Ben had at first
= 3 u
= 3 x 1.40
= $4.20
Amount that Zara had at first
= 4.20 + 35.40
= $39.60
Fraction of money that Zara had left
= 1 -
14 =
34 Amount that Zara had at first = 4 p
4 p = 39.60
1 p = 39.60 ÷ 4 = 9.90
Amount that Zara had left
= 3 p
= 3 x 9.90
= $29.70
Answer(s): $29.70
