Assuming this, you have to start by writing two equations from the information provided:
180 total tickets were sold
x+y=180
they made $590 and adult tickets cost $4 and kids tickets cost $2
180=4x+2y
lets solve for x in the first equation:
x=180-y
we can plug this into the second equation and solve for y
590=4(180-y)+2y
590=720-4y+2y
590=720-2y
-130=-2y
y=65
we can plug this into the first equation and solve for x:
x+65=180
x=115
I hope this helps.
The hours worked at the babysitting job is 6 hours.
The hours worked at the barber shop is 3 hours.
<h3>What are the hours worked at the babysitting job?</h3>
Given the two linear equations:
x + y = 9 equation 1
15x + 9y = 117 equation 2
Multiply equation 1 by 9
9x + 9y = 81 equation 3
Subtract equation 3 from 1
36 = 6x
x = 6
<h3>What are the hours worked at the barber shop?</h3>
Substitute for x in equation 1
6 + y = 9
y = 9 - 6
y = 3 hours
