"Get $10 off if you spend $75 or moret" Carolina wonders how many paintballs sheneeds to buy along with the entrance fee to get the promotionSkLet B represent the number of paintballs that Carolina buys.Lineside1) Which inequality describes this scenario?Choose 1 answer:re18 +0.08B < 7518 +0.08B > 75QuePrac18+ 0.08B < 1018 +0.08B > 102) What is the smallest number of paintballs that Carolina can buy along with the entrance fee to get thepromotion?

Answer 1

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

$\begin{gathered} 18+0.08B=75 \\ 0.08B=75-18 \\ B=\frac{57}{0.08}=712.5\text{ } \end{gathered}$

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