Hilda received $30 more pocket money than Elyse each month. Both of them spent $160 per month and saved the rest. After a few months, Hilda saved $1550 but Elyse only saved $1250.

1. What was Hilda's monthly pocket money?
2. Elyse wanted to save a total of $2500. How many more months did she need in order to save this amount?

(a)
Total amount that Hilda saved more than Elyse
= 1550 - 1250
= $300

Number of months taken for each of them to save their amounts
= 300 ÷ 30
= 10

Amount that Hilda saved each month
= 1550 ÷ 10
= $155

Hilda's monthly pocket money
= 155 + 160
= $315

(b)
Elyse's monthly pocket money
= 315 - 30
= $285

Amount that Elyse saved each month
= 285 - 160
= $125

Remaining amount that Elyse needed to save
= 2500 - 1250
= $1250

Number of more months that Elyse needed to save the remaining $1250
= 1250 ÷ 125
= 10

Answer(s): (a) $315; (b) 10
