Question

Suppose the new actual number of pizzas sold today was 60. The original previous day sold was 65. Describe the number of pizzas sold as a percent increase or decrease (aka Percent of Change), rounded to the nearest hundredth.

Answer 1

Answer: 1) Pizzeria must sell 78 pizzas for receiving the bonus.
2) The number of pizzas sold is decreased by Approximately 7.69 %.
Explanation:
1) The number of pizza sold yesterday = 65,
The target for receiving the bonus = 20% more than the number of pizza sold yesterday
= 20% more than 65,
= 65 + 20% of 65 ( 1% = 0.01 ⇒ 20% = 0.2 )
= 65 + 0.2 × 65
= 65 + 13 = 78.
Hence, they must sell 78 pizzas for receiving the bonus.
2) If the actual number of pizza sold today = 60
⇒ Total reduction in the number of pizza = 65 - 60
= 5
Thus, the percentage decrease in the number of pizza
