The problem in the image states:

"Dave pays $1.75 for a school lunch on days when he doesn't bring his own lunch to school. One week he bought a school lunch on Monday, Wednesday, Thursday, and Friday. How much did he spend on school lunches that week?"

To calculate the total cost Dave spent on lunches:

He bought lunch on 4 days: Monday, Wednesday, Thursday, and Friday.

\[
\text{Total cost} = 1.75 \times 4 = 7.00
\]

So, Dave spent **$7.00** on school lunches that week.

Would you like any further explanation or details? Here are some related questions you might find useful:

1. How do you calculate the total amount for multiple identical items?
2. If Dave skipped one lunch day, how much would he spend in that case?
3. What if the price per lunch increased by $0.50, what would his new total be?
4. How much would Dave spend if he bought lunch every day for two weeks?
5. How can you quickly check the multiplication of decimals like $1.75?

**Tip:** When multiplying by whole numbers, think of it as repeated addition. In this case, $1.75 four times means $1.75 + $1.75 + $1.75 + $1.75.
