Explanation;

Sales tax is computed as the product of the price times the tax rate in % divided by 100:

Sales tax = price × tax rate / 100

Here is each compute:

$299 × 4% = $299 × 4/100 = $11.96

$6,750 × 7% = $6,750 × 7/100 = $ 472.50

$76.50 × 5.2% = $76.50 × 5.2/100 =  $3.98

$18.32 × 3.9% = $18.32 × 3.9/100 = $0.71

$5.95 × 6.2% = $5.95 × 6.2/100 = $0.37

$13.89 × 4.3% = $13.89 × 4.3/100 = $0.60

$768.43 × 3.7% = $768.43 × 3.7/100 = $28.43

$6.49 × 5.8% = $6.49 × 5.8/100 = $0.38

$23.86 × 7.1% = $23.86 × 7.1/100 = $1.69

$12.98 × 3.9% = $0.51

answer: i'm not sure

step-by-step explanation:

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
