First you want to change the 20% into a decimal which is .20
Next you want to multiply 90 by .20 because that will give you the answer for 20% of 90

We just need to <u>plug in 7 for B! </u>
Let's do it !
2 + (10 - 7) 
<em>We always start with the parenthesis first ! It's just a rule in math :) </em>
10 - 7 = ?
10 - 7 = 3 
Now we have ... 
2 + 3
