Which rate describes a unit price

$0.01 for 12 seconds

$0.25 for 5 minutes

$1.00 for 4 hours

$5.00 for 1 day

Step-by-step explanation:

$ 5.00 for 1 day is a unit price

A unit price is the cost of 1 item, or 1 measurement, or 1 time.

another words, 1.00 for 4 hrs IS NOTbut $ 0.25 for 1 hr IS.

and $ 0.25 for 5 minutes IS NOT...but $ 0.05 for 1 minute IS.

and $ 0.01 for 12 seconds IS NOT, but $ 0.00083 per second IS

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
