This is a Part Whole question.
| Spend | saved | total | |
| Joan | 7.50u | 2.5u | 10u |
| Kamil | 7.50u | 0.5u | 8u |
2.5u – 0.5u = 24
2u = 24
1u = 24 ÷ 2 = 12 weeks
2.5u = 12 × 2.5 = $30
0.5u = 12 × 0.5 = $6

10 – 8 = 2
24/2 = 12 (number of weeks)
(10 – 7.50) x 12 = 30 (Joan)
(8 – 7.50) x 12 = 6 (Kamil)
Ans : Joan — $30; Kamil — $6.

Suggested answer:
Every week, Joan will save $2 more than Kamil.
$24 / $2 = 12
In 12 weeks time, J will save $24 more than K.
If they spent $7.5 each week each, J will save $2.50 and K will save $0.50 per week.
$2.50 x 12 = $30
$0.50 x 12 = $6
In 12 weeks time, Joan will save $30 and Kamil will save $6
