Question

Alexis and tasha challenge each other to a typing test. Alex typed 54 words in one minute which was 123% of what tasha typed. how many words did tasha type in one mintue

Answer 1

The relationship between what Alex typed and what Tasha typed can be represented by a simple equation.
Where: 'A' the number of words Alex typed in a minute and T is the number of words typed by Tasha in a minute. 
$A = (1.23)T \\ 54 = (1.23)T \\ \frac{54}{1.23} = T \\ T = 43.9$

Therefore Tasha typed 43.9 words in one minute. 
Hope this helps!
