Answer:
Part A: 90; Part B: 24.
Step-by-step explanation:
The number of blueberry muffins is 40% of the total number of muffins.
Part A: There are 36 blueberry muffins. 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: 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.
The baker:
- Baked 90 muffins on Monday
- Baked 24 Blueberry muffins on Tuesday
On Monday. The baker baked 36 blueberry muffins and this is 40% of the total she makes. Assuming the total is x, the expression would be:
36 = x × 40%
36 = 0.4x
x = 36 / 0.4
= 90 muffins in total
On Tuesday, she makes 60 muffins of which blueberry muffins are 40%:
= 60 × 40%
= 24 blueberry muffins
In conclusion, the Baker baked 90 muffins in total on Monday and 24 blueberry muffins on Tuesday.
