A total of 937 people attended the play admission was $2.00 for adults and $0.75 for students. The total ticket sales amounted t
mamaluj [8]

612 students attended and 325 adults attended the play

<h3><u>Solution:</u></h3>

Let "s" be the number of students attended the play

Let "a" be the number of adults attended the play

Cost of 1 adult ticket = $ 2

Cost of 1 student ticket = $ 0.75

<em><u>Given that total 937 people attended the play</u></em>

number of students + number of adults = 937

s + a = 937 ---------- eqn 1

<em><u>The total ticket sales amounted to $1,109</u></em>

number of adults x Cost of 1 adult ticket + number of students x Cost of 1 student ticket = 1109

a \times 2 + s \times 0.75 = 1109

2a + 0.75s = 1109 ---- eqn 2

<em><u>Let us solve eqn 1 and eqn 2</u></em>

From eqn 1,

s = 937 - a -------- eqn 3

<em><u>Substitute eqn 3 in eqn 2</u></em>

2a + 0.75(937 - a) = 1109

2a + 702.75 - 0.75a = 1109

1.25a = 1109 - 702.75

1.25a = 406.25

a = \frac{406.25}{1.25}

<h3>a = 325</h3>

From eqn 3,

s = 937 - 325

<h3>s = 612</h3>

Thus 612 students attended and 325 adults attended the play
