⦁ Suppose the actual number of pizzas sold today was 66. Describe the number of pizzas sold as a percent increase or decrease.

Answer 1

Answer:

a. 90 pizzas

b. 12% decrease

Step-by-step explanation:

To receive a bonus, there must be 20% increase in the number of pizzas

Thus;

20% of 75 = 20/100 * 75 = 1500/100 = 15

So the number of pizza to be sold to receive the bonus will be 15 + 75 = 90

So now, we have 66 pizza sold today;

We can see that there was a decrease from 75

Percentage decrease will be;

(new value - old value)old value * 100%

= (66-75)/75 * 100%

= -9/75 * 100%

= -0.12 * 100% = -12%

This shows a 12% decrease
