Isha, a super excited Khan Academy user, has increased her points by 75%, percent in a week. She's at 140000 points now. How many points did Isha have on Khan Academy last week?

Respuesta :

Step-by-step explanation:

140,000 = 100 + 75 = 175%

100 % = 175%/1.75 = 140000 / 1.75 = 80,000

she had 80,000 points last week.
