Answer: After her purchases, the change in the amount of money that she had is $7.

Explanation:

Since we have given that

Number of pounds of apple = 4

Cost per pounds = $2

Total cost of apple would be


2* 4=\$8

Number of heads of lettuce = 2

Cost of per lettuce = $1

So, Total cost of lettuce would be


2* 1=\$2

Total amount for apple and lettuce would be


\$8+\$2=\$10

Amount for off = $3

So, it becomes


\$10-\$3=\$7

Hence, after her purchases, the change in the amount of money that she had is $7.
