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

A) 18 + 0.08B ≤ 75

B) 18 + 0.08B ≥ 75

C) 18 + 0.08B ≤ 10

D) 18 + 0.08B ≥ 10

2) What is the smallest number of paintballs that Carolina can buy along with the entrance fee to get the promotion?

paintballs

Look at this system of equations. -3x + 3y = 12 y = x + 4 the solution set of this system is best explained by which of these statements? a) the graphs of the equations are the same line because the equations have the same slope and the same y-intercept. the system has infinitely many solutions. b) the graphs of the equations are parallel lines because they have the same slope but different y-intercepts. the system has no solution. c) the graphs of the equations are lines that intersect at one point because the equations have the same slope but different y-intercepts. the system has exactly one solution. d) the graphs of the equations are lines that intersect at one point because the equations have the same slope and the same y-intercept. the system has exactly one solution.
