Advanced tickets for a school play went on sale. the price of each student ticket was $4 and everyone else paid $5. on the first day, no more than $80 in tickets were sold. describe and explain the possible values of s, the number of tickets sold, and e, the number of tickets sold to nonstudents.

Step-by-step explanation:

Let s be the number of tickets sold.

Let e be the number of tickets sold to non students.

The price of each student ticket was $4, So, total price for s tickets will be 4s.

And everyone else paid $5, so total price for e tickets is 5e.

Now, on the first day, no more than $80 in tickets were sold.

Hence, mathematically we can denote this as:

Now, the minimum values of e and s can be 0, as only whole numbers can be the answer.

When we have s = 0, we get e ≤ 16 and when we have e = 0, then we get s ≤ 20.

Hence, the values of s lies between 0 to 20 and the values of e lies between 0 and 16.

Also, the greatest number of student tickets sold can be 20 and the greatest number of non-student tickets sold will be 16.

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
