Answer:
Part A: Â 90; Part B: Â 24.
Step-by-step explanation:
The number of blueberry muffins is 40% of the total number of muffins.
Part A: Â There are 36 blueberry muffins. Â This is 40% of the unknown number of muffins, x; this gives us
36 = 0.4x
Divide both sides by 0.4:
36/0.4 = 0.4x/0.4
90 = x
There were 90 total muffins.
Part B: Â 40% of the total number of muffins, 60, gives us the unknown number of blueberry muffins:
0.4(60) = x
24 = x
There were 24 blueberry muffins.
