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

3,000 pounds of sand is usede to fill sandboxes. 1,000 pounds can fill the big sandbox, and the rest can fill 4 equal-sized smaller sandboxes. how much sand can be put in each of the smaller sandboxes?

Answers

500pounds because 2000 (the left over sand after you fill the big box) divided by 4(smaller sandboxes) is 500

The amount of sand that can be put in each of the smaller sandboxes is 500 pounds.

What is division?

Division is breaking a number up into an equal number of parts.

Given that, 3,000 pounds of sand is used to fill sandboxes. 1,000 pounds can fill the big sandbox, and the rest can fill 4 equal-sized smaller sandboxes.

Amount left after filling the larger box = 3000-1000 = 2000 pounds

To find the equal amount of sand to be filled in 4 smaller boxes, we will divide the amount left to the number of boxes.

= 2000/4

= 500

Hence, The amount of sand that can be put in each of the smaller sandboxes is 500 pounds.

A teacher surveys a sample of students from Lake Middle School. He asks the students where they’d like to go for a field trip. He records these results:

80 choose the aquarium.
60 choose the science center.
30 choose the planetarium.
40 choose the farm.
The teacher wants to figure out the relative frequency of a student choosing the aquarium. He will then estimate how many students out of all 1000 at the school are likely to choose the aquarium.
4) Write and solve a proportion that the teacher can use to estimate how many students in the whole school would choose the aquarium. Show your work.

Answers

Answer:

210 student's

Step-by-step explanation:

80 students chose the aquarium.

60 students chose the science center.

30 students chose the planetarium.

40 students chose the farm.

The students can't vote for more than one place, so you just add all the numbers together.

80 + 60 + 30 + 40 = 210 students

80 choose the aquarium

Answer:

30%

We know if we put the number of records in the end ÷ the number of records previously, we can get the percentage change.

13/10 = 1.3

1.3 - 1 (Because we want to find the increase, not the amount of percentage this is to that)

0.3 = 3/10 = 30%
