Question

The Miller family visited Mama's Kitchen and ordered 4 hamburgers and 3 medium fries and paid $17.35. James ordered a medium drink, a hamburger, and medium fries and paid $6.09. Steven ordered 2 hamburgers, medium fries, and a medium drink for $9.34. How much did each item cost?

Answer 1

Know: 17.35 is equivalent to 4 burgers 3 med fries
6.09 Is equivalent to 1 burger med fries
9.34 8s equivalent to 2 burgers med fries and med drink
So what you want to do is take 6.09 and subtract it from 9.34 which is 3.25. Now 3.25 is your burger price.
What you want to do now is take your 3.25 and multiply it by 4 which would be 13. 17.35 subtract 13 would be 4.
4 divided by 3 is 1.33 which is now the price of a med fries.
now for the drink. 3.25 plus 1.33 is 4.58.
6.09 subtract 4.58 is 1.51
Now you have 3.25 as your burger
1.33 as your fries
1.52 for your drink
