After eating dinner at a restaurant, Alex's bill before tax is $78.00. The sales tax rate is 8%. Alex decides to leave a 20% tip for the waiter based on the pre-tax amount. How much money will Alex pay total, including tax and the tip?

Alex's will pay a total of $99.86

Step-by-step explanation:

Tax Rate:

$78.00+8%

8% of $78.00=6.24

78.00+6.24=84.24

Tip:

20% of 78.00=15.6

Total:

(Bill+Tax) 84.24+(Tip)15.6=$99.86

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables
