Ella and three friends run in a relay race that is 14 miles long. Each person runs equal parts of the race. How many miles does each person run?

Answers

Answer:

3.5 miles

Step-by-step explanation:

We are given that

Total distance covered in a race=14 miles

Total number of persons=4

Each person runs equal parts of the race.

We have to find the miles run by each person.

To find the distance covered by each person we will divide the total distance by total number of persons who took part in a race.

Each person runs =(total\;distance)/(total\;number\;of\;persons)

Each person runs=(14)/(4)

Each person runs=3.5 miles

Hence, each person runs 3.5 miles.
Ella + 3 friends divided by 14 miles. 

14 ÷ 4= 3.5 
So each person ran 3.5 miles

mick paid $2.94 in sales tax on an item that cost $42.00 before tax. At that rate, how much would he pay in sales tax for an item that costs $58.00 before tax?

Answers

Amount of sales tax paid on an item that cost $42.00 is $2.94.

Rate of sales tax paid = 2.94÷42 =0.07 = 7%.

Rate of sales tax paid by Mick is 7%. The question is asking is to find the sales tax he will pay on an item that costs $58 before tax.

Sales Tax paid by Mick on an item costing $58.00 is 7% of $58.00 =0.07 of 58=4.06.

Sales tax paid for an item that costs $58.00 before tax is $4.06.
$62.06

2.94 / 42 = .07 so the sales tax is 7%

Multiply .07 * 58 (you get 4.06) and then add it to 58

a $25 discount is what the discount is.
