Math Problem Statement
Solution
Let's break down and solve the questions on the worksheet:
1. What is the cost per pound?
A customer buys 4 pounds of strawberries for $32. To find the cost per pound, divide the total cost by the number of pounds:
2. How many pounds do you get per dollar?
This is the inverse of the cost per pound. Since strawberries cost $8 per pound, the number of pounds per dollar is:
3. At this rate, how many pounds can you afford for $48?
We know that 1 pound costs $8. To find how many pounds $48 will buy:
4. At this rate, how much will 3 pounds of strawberries cost?
The cost per pound is $8, so to find the cost of 3 pounds:
Summary of Answers:
