Firlakuza [10]

Answer:

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

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!!!

A girl is 21 years old and her brother is a third her age. When the girl is 36, what will be the age of her brother?
AVprozaik [17]
21 divided by 3 = 7

That means the brother is 14 years younger.

36 - 14 = 22

The brother will be 22 years old.

In which of the following cases would you add 7?
amid [387]
Umm. i am not sure if this will help but, i would pick the first one. mainly because, i like to think of it as money, like for example. If i had two separate banks, and in both of them i had seven dollars. If i give seven dollars to a charity and there is nothing left in my bank, i would add my other money from my second bank into my first one. that way i will have money in the bank i would normally go to.
