Question

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?

choose 1 answer:
a) $18 + 0.08b \leq 75$
b) $18 + 0.08b \geq 75$
c) $18 + 0.08b \leq 10$
d) $18 + 0.08b \geq 10$

Explanation:

Step1: Calculate total cost

Total cost = entrance fee + cost per ball × number of balls = $18 + 0.08B$

Step2: Set up inequality for promotion

Promotion requires total cost ≥ $75$, so $18 + 0.08B ≥ 75$

Answer:

B. $18 + 0.08B ≥ 75$
