Answer:
a) How many batches can Alana make if she uses all the flour?
61 batches
b) How much does the flour for one batch cost?
$0.074
Step-by-step explanation:
Alana uses 1 1/4 cups of flour for each batch of blueberry muffins she makes. She has a 5- pound bag of flour that cost $4.49 and contains seventy-six 1/4 cup servings.
a) How many batches can Alana make if she uses all the flour?
All the flour = 76 1/4 cups of flour
Hence
1 1/4 cups = 1 batch of blueberry muffins
Ins
76 1/4 cups = x
1 1/4 × x = 76 1/4 × 1
x = 76 1/4 × 1/1 1/4
x = 76 1/4 ÷ 1 1/4
x = 305/4 ÷ 5/4
x = 305/4 × 4/5
x = 61 batches of blue berry muffins.
Hence, all the flour (76 1/4 cups of flour) = 61 batches of blue berry muffins
b) How much does the flour for one batch cost?
From the question:
She has a 5- pound bag of flour that cost $4.49 and contains seventy-six 1/4 cup servings.
Flour for 1 batch = 1 1/4
Hence:
76 1/4 cups = $4.49
1 1/4 cups = x
76 1/4 x = 1 1/4 × $4.49
x = (1 1/4 × $4.49 ) ÷ 76 1/4
x = 5/4 × 4.49 ÷ 305/4
x = 5/4 × 4.49 × 4/305
x = $0.0736065574
Approximately = $0.074
Hence, flour for 1 batch cost = $0.074
