Wyatt uses 3.15 cups of flour in a recipe that makes 9 shortcakes. cora uses 2.4 cups of flour in a recipe that makes 8 shortcakes. how much more flower per shortcake is needed for cora’s recipe?

We know that

1) Wyatt uses 3.15 cups of flour in a recipe that makes 9 shortcakes
so
3.15 cups> to make 9 shortcakes
x cups> 1 shortcakes
x=3.15/9> x=0.35 cup/shortcakes

2) Cora uses 2.4 cups of flour in a recipe that makes 8 shortcakes
so
2.4 cups> to make 8 shortcakes
x cups> 1 shortcakes
x=2.4/8> x=0.30 cup/shortcakes

difference=[0.35-0.30]=0.05 cup/shortcake

Cora uses 0.05 cup of flour less per shortcake than Wyatt

Od. 130 degrees because if you add them together you get the 130

Okay so it will be 1123
