the fixed entry is 18 $

and per ball price is 0.08 $

so the equation of expenditure is 18 + 0.08 B

here, B = no. of balls

to get the promotion offer she needs to spend 75 $ or more

so total expenditure should be 75$ or more in order to get the offer.

that is


18+0.08B\ge75

so the answer is option B

2)

for the smallest number of paintballs that Carolina can buy along with the entrance fee to get the promotion is


\begin{gathered} 18+0.08B=75 \\ 0.08B=75-18 \\ B=(57)/(0.08)=712.5\text{ } \end{gathered}

so the no. of the balls are 713 in order to get the promotion of 75 $
