Last year, a 1.6-gallon container of ice cream sold for $5.99. This year, the same ice cream, now in a 1.2-gallon container, sells for the same price of $5.99. By what percentage was the weight of a container of the ice cream reduced? A. 75% B. 25% C. 60% D. 40%​

Answers

Answer:

25% is the answer

Step-by-step explanation:

From last year to this year, the weight of the container is reduced by  

B. 25%

What is the percentage?

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, Last year, a 1.6-gallon container of ice cream sold for $5.99. This year, the same ice cream is now in a 1.2-gallon container.

So, The amount of icecream increased this year is,

= (1.6 - 1.2) gallons.

= 0.4 gallons.

Now to obtain percentage change we'll divide the net amount change by the original amount and multiply it by 100% which is,

= (0.4/1.6)×100%.

= 0.25×100%.

= 25%.

how to find the sale price of an item that has been discounted 25%

Answers

Answer:

Multiply the normal price of the item by .25 and then subtract that from the normal price.

Step-by-step explanation

[tex]x -(x*.25)[/tex]  

x is the item

Step-by-step explanation:

100%-25%= discounted price= 75%

You do the discounted price divided by 75 to find 1%

do that times 100 to find the pre-discounted price.

e.g

find the original price of a sweater when it was on sale of 25%. the sale price is £15.00.

£15.00 = 75%

15.00 divided by 75 = 1% =£0.20

£0.20 x 100 = pre-sale price = £20.00

The price of the sweater before the sale is £20.00.

Group of answer choices

a1 = 3; an = an-1 + 1

a1 = 1; an = an-1 + 3

a1 = 1; an = an+1 + 3

a1 = 3; an = an+1 + 1

Answers

Given:

Lee has 3 dog walking customers.

Each month he gains another customer.

To find:

The arithmetic sequence that represents the number of customers he has.

Solution:

Initial number of customers = 3

First term : [tex]a_1=3[/tex]

Each month he gains another customer.

Common difference : [tex]d=1[/tex]

Recursive formula of an AP is

[tex]a_n=a_{n-1}+d[/tex]

where, d is common difference.

Substituting d=1, we get

[tex]a_n=a_{n-1}+1[/tex]

So, the required arithmetic sequence is [tex]a_n=a_{n-1}+1[/tex], where [tex]a_1=3[/tex].

Therefore, the correct option is A.

Answer:

4/21

Step-by-step explanation:

first you need to make them both fractions, not mixed numbers. so it would be 2/5 divided by 21/10. then you flip the second number so you can multiply it : 2/5 * 10/21. 5 and 10 are divisible by 5 so you can cross 5 out and make a 1 and cross 10 out and make a 2: 2/1 * 2/21. then multiply and you get 4/21!

Adam, Barry, and Charles visited a small farmers market last Saturday. Adam purchased 3 dozen eggs, 1 wheel of cheese, and 5 pounds of potatoes. Barry bought 1 dozen eggs and 10 pounds of potatoes, while Charles purchased 2 dozen eggs and 2 pounds of potatoes. If Adam’s bill was $38.25, Barry’s $36.50 and Charles’ $17.20, how much did a dozen eggs, a wheel of cheese and a pound of potatoes cost?

Answers

Answer:

Dozen eggs = $5.5

Wheel of cheese = $6.25

Pound of potatoes = $3.1

Step-by-step explanation:

Let the cost

Dozen of egg = x

Wheel of cheese = y

Pound of potato = z

We will form linear equations using the information given in the question

Adam purchased 3 dozen eggs, 1 wheel of cheese, and 5 pounds of potatoes

3x + y + 5z = 38.25 ................(1)

Barry bought 1 dozen eggs and 10 pounds of potatoes

x + 10z = 36.50 ............(2)

Charles purchased 2 dozen eggs and 2 pounds of potatoes

2x + 2z = 17.20  .................(3)

solving 2 and 3

x = $5.5  and z = $3.1

substitute these values in equation 1

we get

y = $6.25

The cost

Dozen eggs = $5.5

Wheel of cheese = $6.25

Pound of potatoes = $3.1
