Answer: She paid $66.33
Step-by-step explanation:
The overall amount that you paid for the video game was 87.95. She got 27.79 back as a refund. So you subtract what she paid from her refund. 87.95-27.79 = 60.16. She also had to pay a fine for the video game. So you add the fine to the amount. 60.16+6.17 = 66.33.
Overall, she paid 66.33.
Everything should add up to 100%. So do
20 + 40 + 10 + 5 = 75
Now subtract 75 from 100
100 -75 = 25
25%
Answer:
y = 3/4x - 2
Step-by-step explanation:
slope intercept form: y = mx + b
y-intercept(when x= 0) is given by b
slope is given by m
lets find the slope using the two given points, (4,1) and (8,4)
m = y2-y1 / x2-x1
m = 4 - 1 / 8 - 4
m = 3/4
Now use any of the given points to begin writing your equation, which will help you find the y intercept - ill use (4,1).
1 = 3/4(4) - b
1 = 3 - b
b = -2
now you have m and b so you can finish writing your equation.
y = mx + b
y = 3/4x - 2
X<3 or X>1
move constant to the right side and change the sign
