Question

One week, Isabelle bought 2 bags of apples and 3 bags of oranges. The next week, she bought 1 bag of apples and 2 bags of oranges. If a represents the cost of each bag of apples and r represents the cost of each bag of oranges, which expression could Isabelle use to calculate the difference between the amounts she spent each week?

Answer 1

Answer:

a + r

OR  

- a - r

Step-by-step explanation:

First week cost of Isabelle:

2 bags of apples at a price of  each, so total cost is

3 bags of oranges at a price of  each, so total cost is

Sum of these two:  2a + 3r

Second week cost of Isabell:

1 bag of apple at a price of  each, so total cost is

2 bags of oranges at a price of  each, so total cost is  

Sum of these two: a + 2r

Depending on the price of bags of apples and oranges, the second week can cost more, or the first week's total could be more.

If 2nd weeks total is more than 1st week's total:

The difference is 2nd week's total minus first week's total: = - a- r

If 1st weeks total is more than 2nd week's total:

The difference is 1st week's total minus second week's total: = + a + r
