Tina received $70 more pocket money than Julie each month. Both of them spent $140 per month and saved the rest. After a few months, Tina saved $1750 but Julie only saved $1400.

1. What was Tina's monthly pocket money?
2. Julie wanted to save a total of $2240. How many more months did she need in order to save this amount?

(a)
Total amount that Tina saved more than Julie
= 1750 - 1400
= $350

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

Amount that Tina saved each month
= 1750 ÷ 5
= $350

Tina's monthly pocket money
= 350 + 140
= $490

(b)
Julie's monthly pocket money
= 490 - 70
= $420

Amount that Julie saved each month
= 420 - 140
= $280

Remaining amount that Julie needed to save
= 2240 - 1400
= $840

Number of more months that Julie needed to save the remaining $840
= 840 ÷ 280
= 3

Answer(s): (a) $490; (b) 3
