Answer:
Total Sales
$1.5a + $180
Explanation:
Let s be the number of student tickets sold.
The total of s and b tickets is therefore ≤120. a + b ≤ 120. We can then say that b = ≤(120 - a).
Total sales is the sum of adult and student tickets sold at their respective prices:
Adult = a*($3)
Student = b*($1.5), or = ≤(120-a)($1.5)
Total = $3a ≤ $1.5(120-a)
Total Sales = $3a ≤ ($180 -$1.5a)
Total Sales
$1.5a + $180
