Let t represent Todd's age now.
.. 4(t -3) -(t -3) = 81 . . . . . . 3 years ago, their differnce in ages was 81.
.. 3t -9 = 81
.. t = (81 +9)/3 = 30
Todd is 30 now.

The answer is 180
Step-by-step explanation:
So to start off you have to turn 20% into a decimal and that is .20.
Next you need to mutiply 225 and .20 and you will get 45 (that means it is $45 off)
