The answer is 14.50. Hope that helped
Y=mx+b
b represents your y-intercept
mx represents your slope
-0.183 = -0.183 / 1
Numerator = -0.183 × 10 × 10 × 10 = -183
Denominator = 1 × 10 × 10 × 10 = 1000
Numerator / Denominator = -183 / 1000
Our simplified fraction is:
= -183/1000
Say the number of adult tickets is x. That means the number of student tickets is 71 less, making it x - 71.
We can add the number of student and adult tickets, because we know their sum is 479.
x + x - 71 = 479
Now, we solve for x.
2x - 71 = 479
2x = 550
x = 275
So, there were 275 adult tickets sold.
