Carolina goes to a paintball field that charges an entrance fee of $18 and $0.08 per ball. The field has a promotion that says, "Get $10 off if you spend $75 or more!" Carolina wonders how many paintballs she needs to buy along with the entrance fee to get the promotion.
Let B represent the number of paintballs that Carolina buys.
1) Which inequality describes this scenario?
The inequality that describes this scenario is:
18 + 0.08B ≥ 75 - 10
Simplifying:
18 + 0.08B ≥ 65
Therefore, the inequality is:
0.08B ≥ 47
B ≥ 588
So, Carolina needs to buy at least 588 paintballs to spend $75 or more and get the $10 off promotion.
