1) The correct equation is:

Option B) 18+0.08B≥75

2)Carolina needs to buy at least 712 paintballs

Explanation:

We are told in the question that:

Carolina goes to a paintball field that charges an entrance fee of $18 and $0.08per ball. The field has a promotion that says, "Get $10 soff if you spend $75more!"

Hence, our inequality equation is:

Let us represent the number of balls as B

$18 +0.08 × B ≥$75

18 +0.08B ≥75

0.08 ≥ 75 - 18

0.08B ≥57

B ≥ 57/0.08

B≥ 712.5

Therefore, Carolina needs to buy at least 712 paintballs.
