Four friends had dinner at a restaurant. the bill was $45.00 and they added a 20% tip. the four friends shared the total cost equally. how much does each person pay?

$13.50

Step-by-step explanation:

We can find the total bill here by multiplying $45 by 1.20, where the 0.20 represents the 20% tip:

1.20($45) = $54

Since the four friends agree to split the bill equally, each pays:

$54/4 = $13.50

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

70.30
