b) $3.75.
c) $3.90.
d) $5.17.

Answer 1

To find Ginger's average daily cost for lunch, add up her total spending for the week and divide it by the number of days.

Step-by-step explanation:

To find the average daily cost, we need to add up Ginger's total spending for the week and then divide it by the number of days.

On Monday and Thursday, she spent $5.43 total.

On Tuesday and Wednesday, she spent $3.54 on each day, so her total spending for these two days is $7.08.

On Friday, she spent $7.89 on lunch.

Adding up her total spending for the week, we get $5.43 + $7.08 + $7.89 = $20.40.

Since there are 5 days in a work-week, her average daily cost is $20.40 divided by 5, which is $4.08.

Therefore, the correct answer is d) $5.17.
