Final answer:
After a 75% decrease in the number of cupcakes from 56, Mrs. Johansen had 14 cupcakes remaining.
Step-by-step explanation:
Mrs. Johansen baked 56 cupcakes for the bake sale. After a 75% decrease, we need to calculate how many cupcakes were left. To do this, we can follow these steps:
- Calculate the number of cupcakes that represent a 75% decrease from the original amount.
- This is done by multiplying the total number of cupcakes by 75%, or 0.75. So, 56 * 0.75 = 42 cupcakes.
- Subtract the decrease from the original amount to find out how many are left.
- Hence, 56 - 42 = 14 cupcakes.
Therefore, Mrs. Johansen had 14 cupcakes left after the sale.
