Percent Problems
If the question asks ‘what is the percent’, grid in the answer without
moving the decimal point.
Lisa bought lunch for her friends. The
cost of the lunch was $64.00 including tax.
Lisa wants to leave a $8.00 tip. What
percent tip did Lisa leave?
Set up a proportion:
x
=
8.00
100 64.00
Because the problem
asked for what percent,
just grid the answer 12.5
Solve 64x = 800
x = 12.5
DO NOT move the
Decimal to .125

it.
Rounding--- We recommend:
Don’t round UNLESS the directions tell you to
do so.
