Carl drove from his home to the beach at an average speed of 50 mph and returned home
along the same route at an average speed of
30 mph. His total driving time for the trip was
2 hours. Solving which of the following systems
of equations yields, x, the time it took for Carl
to drive to the beach and, y, the time spent for
the return trip?

5   1/4   miles per hour

step-by-step explanation:

15   3/4 / 3 = 5   1/4

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
