You can put this solution on YOUR website! Mr. Chin spent money on card games, robots, and science kits in the ratio 7:3:2. The science kits cost $10 less than the card games. How much money did Mr. Chin spend in all?
-----
Equation:
Total cost was 7x + 3x + 2x = 12x
2x = 7x-10
----
5x = 10
x = 2
----
So, total cost = 12x = $24.00
