If the sales tax rate is $8.25 per $100.00.What is the sales tax if the sale amount is $54.80?

$4.52

Step-by-step explanation:

From the question, sales tax rate is $8.25 per $100, this means that for every $100 item sold, $8.25 will be paid as sales tax.

Sales tax for 54.80 = x

Step 2: write the equation as;

8.25 = $100

Sales tax for $1 item will be (divide both sides by 100

$8. 25/ 100 = $0.0825

Step 3: determine the sales tax on $1 item, that is if sales tax $1 item = $0.0825

Sales tax for $54.80 item will be 0.0825 x 54.80

= $4.52

step-by-step explanation:

i took the test: )

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
