Emily received $30 more pocket money than Usha each month. Both of them spent $100 per month and saved the rest. After a few months, Emily saved $1550 but Usha only saved $1250.
- What was Emily's monthly pocket money?
- Usha wanted to save a total of $2250. How many more months did she need in order to save this amount?
(a)
Total amount that Emily saved more than Usha
= 1550 - 1250
= $300
Number of months taken for each of them to save their amounts
= 300 ÷ 30
= 10
Amount that Emily saved each month
= 1550 ÷ 10
= $155
Emily's monthly pocket money
= 155 + 100
= $255
(b)
Usha's monthly pocket money
= 255 - 30
= $225
Amount that Usha saved each month
= 225 - 100
= $125
Remaining amount that Usha needed to save
= 2250 - 1250
= $1000
Number of more months that Usha needed to save the remaining $1000
= 1000 ÷ 125
= 8
Answer(s): (a) $255; (b) 8
