Your question isn't complete as you didn't give the sales tax percent. In order to solve the question, let's assume that the sales tax is 6%.
(a) What is the amount of sales tax that Mr. Speer has to pay?
This will be:
= Sales tax percent × Amount charged
= 6% × $300
= 6/100 × $300
= 0.06 × $300
= $18
The sale tax is $18
(b) What is the total amount Mr. Speer has to pay?.
The total amount will be the addition of the amount charged and the sales tax. This will be:
= $300 + $18
= $318
Ok if a student walks 17 meters in 30 seconds he walks 34 meters in a minute 17+17=34 then you take 34(meters in a minute) multiply by 60(minutes in an hour) you get 2040 34x60=2040meters 1609.34 meters equal a mile 2040-1609.34=430.66 meters left theres 1.09361yards in a meter so 430.66x1.09361=470.97yards
so i guess you could say a student would walk 1mile and 470.97 yards if he walked 17 meters in 30 seconds for an hour straight
p.s it made sense in my head
