tax, while auto rentals are taxed an additional 5%, for a total of 10% tax.
alan bought $90 worth of souvenirs, taxable at the general rate. he also spent
$420 on prepared food and lodging and $510 for a rental car, all before tax.
how much did he spend in total after tax was included?

1105

Step-by-step explanation:

Alan bought $90 worth of souvenir on which he paid 5% tax. Therefore he paid

90×(1.05)= 94.5

Then he spent $420 on prepared food on which 7% tax is charged. Therefore he paid

420×(1.07)= 449.4

Than he uses car on rent for $510 on which 10% tax is charged. Therefore he paid

510×(1.1)= 561

Therefore the total amount he paid including taxes is 561+449.4+94.5= 1104.9 or 1105 (rounding off)

answer: the common difference is -0.10

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.
