<em><u>The equation used to find the cost of student ticket is:</u></em>

<em><u>Solution:</u></em>
Given that,
A teacher brings $50 to pay for museum admission
She buys an adult ticket for $3.50 and 13 student tickets
Cost of adult ticket = $ 3.50
Let "x" be the cost of each student ticket
Three students arrive late so she buys 3 more student tickets
She has $18.50 left
<em><u>The equation used to find the cost of student ticket is:</u></em>
Cost of adult ticket + 13 student tickets x cost of each student ticket + 3 student ticket x cost of each student ticket = 50 - 18.50

Thus the above equation is used
