Answer:
28 biscuits.
Step-by-step explanation:
Belinda has 10 cups of flour
She uses 3 cups to make a loaf of bread
She uses [tex]\frac{1}{4}[/tex] cup of the remaining flour for each biscuit she wants to make.
There are 10 - 3 = 7 cups of flour remaining
[tex]\frac{1}{4}[/tex] cup of flour makes -> 1 biscuit
7 cups of flour will make;
7 × 1 ÷ [tex]\frac{1}{4}[/tex] = 7 × 4 = 28 biscuits
