Question

The graph shows the relationship between the number of cups of flour and the number of cups of sugar in Angela's brownie recipe.

The table shows the same relationship for Jaleel's brownie recipe.
Jaleel and Angela buy a 12-cup bag of sugar and divide it evenly to make their recipes.
If they each use ALL of their sugar, how much FLOUR do they each need?

Answer 1

Angela needs 3 cups of flour, Jaleel 4

Explanation:

Both get 6 cups of sugar when they divide it even. Then you set 6 for x and "solve" for y.

For Angela you can read the number from the graph, y = 0,5x

Angela needs a half cup of flour per whole cup of sugar.

Jaleel: get 6 cups of sugar too, you can easily double the cups from the table, which means 4 cups of flour with 6 cups of sugad
