Hello! I believe the answer to your question is C (hours). If t is the amount of time it takes, hours is a unit of time, therefore I assume that would be your answer. :)
Answer:
y = -
x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
3x + 4y = 8 ( subtract 3x from both sides )
4y = - 3x + 8 ( divide all terms by 4 )
y = -
x + 2 ← in slope- intercept form
4.68/12 = 0.39 per ticket
4.50/10 = 0.45 per ticket.
So, we are better off taking 12 tickets for $4.68
Hope this helps!
