Answer:
The two bags of green grapes are a lower unit rate.
Explanation:
A bag of red grapes is $4 and two bags of green grapes is $7.50. If you buy two bags of red grapes the total amount of money you are spending is $8. If you buy two bags of green grapes the total is $7.50. If you divide $7.50 by two you get $3.50. This means that for one bag of green grapes it is $3.50. Therefore the two bags of green grapes are a lower unit rate.
