the members of the drama club have 100 tickets to sell to the school play. students pay $5 per ticket, and nonstudents pay $10 per ticket. the drama club needs to collect at least $800 in total ticket sales. the system of inequalities represents the number of student tickets, s, and the number of nonstudent tickets, n, the members must sell.\ns + n ≤ 100\n5s + 10n ≥ 800\nwhat is the maximum number of student tickets that can be sold if the drama club meets its sales goal?\n40\n60\n80\n100
Answer
Explanation:
Step1: Express $n$ from the first - inequality
$n\leq100 - s$
Step2: Substitute $n$ into the second inequality
$5s+10n\geq800$, substituting $n$ gives $5s + 10(100 - s)\geq800$.
Step3: Expand and solve the inequality
Expand: $5s+1000 - 10s\geq800$. Combine like - terms: $- 5s\geq800 - 1000=-200$. Divide both sides by $-5$ and reverse the inequality sign: $s\leq40$.
Answer:
