Question

Our school play offered student tickets at $3.00 each and

adult tickets at $5.00 each. Opening night 300 people
attended and the total amount of money collected was
$1 210.00. How many students attended?

Answer 1

The answer is 145

Explanation:

X + Y = 300

3.00x + 5.00y = 1210.00

Y= 300 - X

3x + 5(300 - x) = 1210

3x + 1500 - 5x = 1210

Subtract 1500 from each side

3x -5x = -290

Add the x's

-2x = -290

Divide -2 to each side

X = 145
