so she buys 3 more student tickets. She has $18.50 left. Which equation can you use to find the
cost of a student ticket?

a. 13x + 3x = 50 - 18.50 c. 13x + 3.50 +3x = 50
b. 13x + 3.50 + 3x + 18.50 = 50 d. 3x = 3.50 + 13x

The equation used to find the cost of student ticket is:

[tex]13x + 3.50 + 3x + 18.50 = 50[/tex]

Solution:

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

The equation used to find the cost of student ticket is:

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

[tex]3.50 + 13x + 3x = 50-18.50\\\\13x + 3.50 + 3x + 18.50 = 50[/tex]

Thus the above equation is used
