Jack and Albert went shopping with a total amount of $247. They had $209 left after shopping. Jack's remaining money was 4 times the amount he paid for. Albert's remaining money was 7 times the amount he had spent.

1. How much did Albert spend?
2. How much did Albert bring along for shopping?

	Jack	Albert	Total
Before	5 u	8 p	247
Change	- 1 u	- 1 p	- 38
After	4 u	7 p	209

(a)
Amount that Jack and Albert spent
= 247 - 209
= $38

Amount that Jack and Albert spent
= 1 u + 1 p

1 u + 1 p = 38
1 u = 38 - 1 p --- (1)

Amount that Jack and Albert had left
= 4 u + 7 p 

4 u + 7 p = 209
4 u = 209 - 7 p --- (2)

Make u the same.

(1) _{x 4}
4 u = 152 - 4 p --- (3)

(3) = (2)
152 - 4 p = 209 - 7 p 
7 p - 4 p = 209 - 152

3 p = 57

1 p = 57 ÷ 3 = 19

Amount that Albert spent = $19

(b)
Amount that Albert brought along
= 8 p
= 8 x 19
= $152

Answer(s): (a) $19; (b) $152
