The questions being asked are very vague and confusing. This is the best I could do with the information presented.
Answer
1. This situation is about the prices of different items at a supermarket during the weekend sale.
2.
The quantities range. They vary between per pound, per package, per head, etc.
3."What is the total price of all the items combined?"
"How much would it cost to buy 4 pounds of grapes and 1 package of crackers?"
"How much more is a pound of Swiss cheese compared to a head of lettuce?"
"How many times less is the price of one squash to a head of avocados?"
4.
"How much would it cost to buy 4 pounds of grapes and 1 package of crackers?"
The price of a pound of grapes is $2.50. Times 4 this equals $10. Plus, the price of a package of crackers, $1.48, equals $11.48.
I hope this helps.
