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

Answer:

She needs to buy 712.5 balls

Step-by-step explanation:

Let B represent the number of paintballs that Carolina buys

How many paintballs she needs to buy along with the entrance fee to get the promotion.

From the above question, we have the following Inequality equation

$18 + $0.08 × B ≥ $75

18 + 0.08B ≥ 75

18 + 0.08B = 75

0.08B = 75 - 18

0.08B = 57

B = 57/0.08

B = 712.5
