A wallet contains the same number of one, five and ten dollar bills. The bills total $176. How many of each type of bill does the wallet contain?

11 of each bill. Explanation: Plug the numbers into an equation to explain the addition. This could be 1x+5x+10x=176, because the wallet contains the same amount of each bill (the x variable). You now have to add like-variables, so add all of the numbers with x. You should now have 16x=176. Now, divide both sides by 16 to isolate the variable, and you’ll get your answer. x= 11. There are 11 of each bill.

If i think this is what your asking, he should look at the grams or pounds/ounces and compare the to their cost then max can identify which one is proportional and which is not ( i think xd)
