Answer: The tip is $17
Step-by-step explanation: You multiply $85 by .2 to get this answer.
Answer: (12,0)
Steps:
First, put the equation in slope-intercept form.
y=mx+b
1.5x + 4.5y =18
Subtract 1.5x from both sides.
4.5y =-1.5x +18
Divide both sides by 4.5 to isolate y.
y = -1/3x + 4
Then replace y with 0 because the point for the x-intercept is exactly on the x-axis so the y=0.
0 = -1/3x + 4
Subtract 4 from both sides
-4 = -1/3x
Divide both sides by -1/3 to isolate the x
12=x
One hour = 60 minutes
60-15=45 so I would just add your 45 minutes to your 2:15
2:15+:45= 3:00
so your answer will be 3:00 :)
Change percent to decimal which is 0.35 and multiply it by 550 to get 192.5 which is the amount taken off from the original price. So the total price after the discount is 357.5$
