Answer:
There were 40 student tickets sold.
Step-by-step explanation:
First I set up equations to represent this situation.
4x+3y=380
x+y=105
x represents the adult tickets and y represents the student tickets.
I can solve this with the elimination method. I want to cancel out the x so I will multiply every term in equation 2 by -4.
4x+3y=380
-4x-4y=-420
Now I combine like terms.
-y=-40
I can divide the negative one from both sides.
y=40
50% markup of $111.00 is the same as increasing 111 by half
50% of 111 = 55.5
Then add 55.5 on 111 = $166.50
Final value $166.50
Step-by-step explanation:
if you're asking for distance then,
V = s / t
50 mph = s / 3 hrs
50 mph × 3 hrs = s
150 miles = s
