Answer:
The tax rate is not needed
Total bill cost = $13
Step-by-step explanation:
Given that :
Tip left = 2.60
Tax = 5%
Tip left = 20% of after tax cost
To calculate the total bill amount, we do not need information about the tax rate.
Since the total amount paid = after tax amount
Tip left = 2.60 is equal to 20% the after tax cost
Let after tax amount = t
Then,
20% of t = 2.60
(20/100) * t = 2.60
0.2t = 2.60
t = 2.60/0.2
t = 13
Hence, total bill is $13
Parallel lines have the same slope.
Find the slopes of segments DE and AB and show they are equal.
Slope of DE:
(y1/2 - y1/2)/((x1 + x2)/2 - x1/2) = 0/(x2/2) = 0
Slope of AB:
(0 - 0)/(x2 - 0) = 0/x2 = 0
Both segments have slope 0.
Since the slopes are equal, the segments are parallel.
