Question

Isha, a super excited Khan Academy user, has increased

her points by 75% in a week. She's at 14,000 points
now.
How many points did Isha have on Khan Academy
last week?

Answer 1

Answer: 8000 points last week.

Explanation:

If she has increased by 75% in a week to get 14000 points then we can say that 175% times a number has to equal 14,000 , where the number of points she had last week.

175% * x = 14000

1.75x =14000 Divide both sides by 1.75

x= 8000

So she had 8000 points last week.

Check:

175% * 8000= 14000

1.75 * 8000 = 14000

14000 = 14000
