Find last years salary if after 3% pay raise, this years salary is $34505

     $34,505

s = = $33,500

         1.03

Step-by-step explanation:

Last year's salary was 1.00 s.

A 3% pay raise would thus amount to 0.03s.

This would equal this year's salary:  $34,505.

Thus, 1.03s = $34,505; find s, which was last year's salary.

Dividing both sides by 1.03, we get:

     $34,505

s = = $33,500

         1.03

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.
