The retail price is 100% of the cost, and when 10% is taken off, that is the new price of the sweater.
100%-10%=90%
Then you convert the percentage to decimal and multiply the decimal with the retail price.

90%=0.9
0.9(40)=36
The new price of the sweater is $36.

Answer:

Step-by-step explanation:

Complete Question

Select the correct month.

Listed are the quantities of green grapes Martha bought for four months and the amount that she spent on them. In May, she bought 2 pounds of grapes for $5.40, in which month was the unit price the same as it was in May?

January

2 pounds for $7.40

February

4 pounds for $10.80

March

5 pounds for $11.65

April

3 pounds for $7.50

Solution

In May, Martha bought 2 pounds of grapes for $5.40.

The unit price per pound = (5.40/2) = $2.70 per pound of grapes.

We can then do this for the months given to obtain which month in which the unit price is the same as it was in May?

For January

She bought 2 pounds of grapes for $7.40

Unit price per pound = (7.40/2) = $3.70 per pound of grapes.

For February

Martha bought 4 pounds of grapes for $10.80.

Unit price per pound = (10.80/4) = $2.70 per pound of grapes.

March

She bought 5 pounds of grapes for $11.65.

Unit price per pound = (11.65/5) = $2.33 per pound of grapes.

April

She bought 3 pounds of grapes for $7.50.

Unit price per pound = (7.50/3) = $2.50 per pound of grapes.

It is evident that it is in February that the unit price of grapes ($2.70 per pound of grapes) is the same as that of May.

Hope this Helps!!!

faltersainse [42]

The Venn diagram to illustrate this information is given in the image attached.

<h3>What is the Venn diagram about?</h3>

The number of children who took plantain and beans only are:

Let beans = a

Rice = b

Plantain = P

So: a + b = 24 - 9 - 5 = 10

Note that 24 children took plantain.

9 children took only Plantain.

5 took the 3 food items.

So:

b + c = 18 -2 - 5 = 11

a + c = 21 - 3 - 5 = 13

P∩B = a + 5

= 6 + 5 = 11

R ∩ B = C + 5

=7 + 5 = 12

None of the three items of food =

50 - (3 + 2 + 9 + 6 + 4 + 7 + 5)

= 50 - 36

=14

Tell whether the given value is a solution of the equation: n/12 = 2; n = 26

Anika [276]

Answer:

no, 26 it is not a solution to the equation

Step-by-step explanation:

simply substitute n for 26 since n=26

n/12=2

26/12=2

2.17=2

that does not make sense (since 2.17 is not 2), so, no, 26 is not a solution
