Noah has $300 to spend this school year. He will be purchasing lunches at the rate of $2.25 each day, dd, and buying a pair of $120 shoes. Which inequality reveals how many days Noah can afford to buy lunch?

Question

d ≥ 80
d ≤ 80
d ≥ 133.3
d ≤ 133.3

Answer 1

To find the inequality that reveals how many days Noah can afford to buy lunch, we need to set up an equation. Noah has $300, and each lunch costs $2.25. Therefore, the inequality would be:

2.25d ≤ 300

Where d represents the number of days Noah can afford to buy lunch.

Simplifying the equation:

d ≤ 300/2.25

d ≤ 133.3

The correct inequality is d ≤ 133.3, which means Noah can afford to buy lunch for no more than 133 days.
