I and 4i
let's say if you have i you can automatically think there is a one in front of it so one term like this (i) could look like this 1i and any number with the same variable or letter are like terms
hope this helps
It's 96%
816/850 = 0.96, which is 96%
Hope I helped! ( Smiles )
Basically you need to multiply the percent by the number.
You should go up 3.5 on the Y-Axis and then go up .5 and over 1.
