So we have 11400 +11400×x=12711
this represents the original price plus some percentage of the original price is equal to the new price. now all we need to do is solve for x
so 11400+11400x=12711
subtract 11400 from each side
11400x=1311 now divide both sides by 11400
x=.115 or about 12%
we can. check by finding 12% of the original price.
11400×.12=1368
now add to 11400
11400+1368=12768 so we are a bit over. this is because it is actually 11.5% just depends on how accurate your answer needs to be

Edward is driving a car on the highway. He drives for 28.5 miles in 3/8 of an hour. At this rate, how much distance can he cover
Rom4ik [11]

The distance covered in one hour is 76 miles.

<u>Step-by-step explanation:</u>

Edward drives a car for 28.5 miles.

Therefore, the distance he travels by the car = 28.5 miles.

The time it takes to drive 28.5 miles is 3/8 of an hour.

<u>The formula to find the rate :</u>

Rate = Distance traveled / Time taken in hours.

Here, the distance is 28.5 miles and time is 3/8 hour.

Rate = 28.5/ (3/8)

<u>To find the distance covered in 1 hour :</u>

Let us assume, 'x' be the distance covered in one hour.

Rate = x/1

<u>Now, comparing the rates to find the x value :</u>

⇒ 28.5 / (3/8) = x /1

⇒ x = 28.5 \times  8/3

⇒ x = 228/3

⇒ x = 76

Therefore, the distance covered in one hour is 76 miles.
