Okay, so we already know that 350 people purchased tickets in hour 1:
17.50(350 + ?) = ?
The question states that in the 2nd hour, there was 20% more people. So basically, we solve for 120% of the people from the 1st hour:
17.50(350 + 1.2(350)) = ?
Multiply 1.2 by 350:
17.50(350 + 420) = ?
Add:
17.50(770) = ?
Multiply:
17.50(770) = 13475
$13,475 was the total amount of money.
Answer:
y=3x+12, y- intercept is 12
Step-by-step explanation:
-12x+4y=48
+12x +12x
4y=12x+48
divide by 4
y=3x+12
The equation is linear, as you can write

An integrating factor would be

Multiplying both sides of the ODE by this yields

where the LHS is a derivative:
![\dfrac{\mathrm d}{\mathrm dx}\left[x^{1/3}y\right]=4x^{1/3}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Cmathrm%20d%7D%7B%5Cmathrm%20dx%7D%5Cleft%5Bx%5E%7B1%2F3%7Dy%5Cright%5D%3D4x%5E%7B1%2F3%7D)
Integrating both sides, we get
