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.

Answers

Answer: 1) Pizzeria must sell 78 pizzas for receiving the bonus.
2) The number of pizzas sold is decreased by Approximately 7.69 %.
Step-by-step 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

Lily likes to collect records. Last year she had 10 records in her collection. Now she has 13 records. What is the percent increase of her collection?

Answers

Answer:

30%

Rosemary is driving to Chicago, and she is 84 miles away. She wants to arrive in 1.5 hours. What rate of speed will she have to maintain to arrive in that time?
Group of answer choices

Rosemary needs to maintain 126 mph.

Rosemary needs to maintain 65 mph.

Rosemary needs to maintain 56 mph.

Answers

Answer:

56 mph

Step-by-step explanation:

Process of elimination. 126 mph is much too high because it's more than the distance and they will arrive too early. 65 + 65 ÷ 2 = 97.5, that's more than 84 miles. The reason we divide by 2 is because of the .5. Now all we have is 56 mph. To check, 56 + 56 ÷ 2 = 84

Answer:

56

Step-by-step explanation:

84 / 1.5 = 56
