Gem received $70 more pocket money than Raeann each month. Both of them spent $190 per month and saved the rest. After a few months, Gem saved $1580 but Raeann only saved $1230.

1. What was Gem's monthly pocket money?
2. Raeann wanted to save a total of $2460. How many more months did she need in order to save this amount?

(a)
Total amount that Gem saved more than Raeann
= 1580 - 1230
= $350

Number of months taken for each of them to save their amounts
= 350 ÷ 70
= 5

Amount that Gem saved each month
= 1580 ÷ 5
= $316

Gem's monthly pocket money
= 316 + 190
= $506

(b)
Raeann's monthly pocket money
= 506 - 70
= $436

Amount that Raeann saved each month
= 436 - 190
= $246

Remaining amount that Raeann needed to save
= 2460 - 1230
= $1230

Number of more months that Raeann needed to save the remaining $1230
= 1230 ÷ 246
= 5

Answer(s): (a) $506; (b) 5
