If the average grade of an english class rose from 70 to 85, what is the approximate percent increase?
the percent increase is 14%.
the percent increase is 17%.
the percent increase is 21%.
the percent increase is 35%.

It is a percent increase because going from 70 to 85 is going from a smaller to a bigger number.

The percent increase is 21% approximately.

Step-by-step explanation:

The percent increase or decrease can be found by computing:

We have new=85 and original=70.

Plug in the given values into the formula:

Divide top and bottom by 5:

Putting 3 divided by 14 in my calculator gives:

0.2143 approximately

To convert to a percentage you multiply it by 100 which drags the deicmal over right 2 places:

21.43% approximately

Now let's see what happens if we do a 21.43% on 70. We should obtain something close to 85.

21.43% of 70=.2143*70=15.001

So 70+15.0001=85.001 which is approximately 85.

The approximate percent increase would be 21%

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
