Final answer:
To compare the total amounts spent on apples and cheese, we set up an equation and solve for the cost per pound of apples.
Step-by-step explanation:
To determine if Greg spent the same amount each week, we need to compare the total amount spent on apples and cheese for each week.
Last week, Greg bought 2 1/4 pounds of apples and spent $5.73 on cheese. So, the total amount spent last week is 5.73 + (2 1/4 pounds x cost per pound of apples).
This week, Greg bought 1 4/5 pounds of apples and spent $6.54 on cheese. So, the total amount spent this week is 6.54 + (1 4/5 pounds x cost per pound of apples).
To compare the total amounts, we can set up an equation:
5.73 + (2 1/4 pounds x cost per pound of apples) = 6.54 + (1 4/5 pounds x cost per pound of apples).
We can solve this equation to find the cost per pound of apples, and then substitute it back into the equation to find the total amount.
