adult tickets to the fall play cost $8 and student tickets cost $4. the drama class sold 20 more adult tickets than student tick

andriy [413]

let us repersent the number of student tickets, then 's + 20' is repersenting the number of adult tickets.

The equation for the total tickets can be experssed as the following:

4.00 * s + 8.00 * ( s + 20 ) = 880.00

solving for 's=60', there were 60 student tickets.

60 + 20 = 80

there were 80 adult tickets.

So I kinda forgot how to do this *nervous laughter* um help

1) value of x =60

2) value of x = 3

Step-by-step explanation:

We need to use cross products to solve the proportions of x.

$1.\,\, \frac{3}{5}= \frac{x}{100}$

Solving:

$\frac{3}{5}= \frac{x}{100}\\Cross\,\,multiply\,\,:\\5x=3*100\\5x=300\\x=\frac{300}{5}\\x=60$

So, value of x =60

$2.\,\,\frac{x}{8}=\frac{7.5}{20}$

$\frac{x}{8}=\frac{7.5}{20} \\20x=7.5*8\\20x=60\\x=\frac{60}{20}\\ x=3$

So, value of x = 3
