Answer 1

Hi, Camila

 

Okay, the average is the total of all the scores divided by the number of tests taken.

Let X = the number of tests taken

A = 284/X = 71

Cross multiply:

71X = 284

X = 284/71 =  4 

 

You took 4 tests

Answer 2

Hello Camila

 

Average is the sum of all the individual test points divided by the # of tests.

 

284 / x = 71

 

x = 284 / 71 = 4 tests taken
