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!!!
