Jeremy, Eric, Andy and Jenson went shopping with a total of $553. After shopping, they had a total of $43 left. Eric spent $10. The amount Andy spent was ³₈ the amount spent by Jeremy. The total amount spent by Jeremy and Eric was $42 less than the total amount spent by Andy and Jenson. How much did Jeremy and Jenson spend altogether?

	Jeremy	Eric	Andy	Jenson	Total
Before					$553
Change	- 8 u	- $10	- 3 u	- ?	- $510
After					$43

Total amount that Jeremy, Eric, Andy and Jenson spent
= 553 - 43
= $510

Total amount that Jeremy and Eric spent
= 8 u + 10

Total amount that Andy and Jenson spent
= 8 u + 10 + 42
= 8 u + 52 

Total amount that Jeremy, Eric, Andy and Jenson spent
= 8 u + 10 + 8 u + 52
= 16 u + 62 

16 u + 62 = 510
16 u = 510 - 62
16 u = 448 

1 u = 448 ÷ 16 = 28

Total amount that Eric and Andy spent
= 3 u + 10
= 3 x 28 + 10
= 84 + 10
= $94

Total amount that Jeremy and Jenson spent
= 510 - 94
= $416

Answer(s): $416
