Answer:
Michelangelo
Step-by-step explanation:
So since all of these are off, we know that we need to remove that percent from the price. Lets start with Leonardo.
Leonardo's board was $125 with 25% off so the remaining price is 75%. This means we need to multiply 125 by .75.
125*.75=93.75
Leonardo payed $93.75
Now we need to do Donatello. His board was $110 with 10% off so we need to multiply 110 by .9 to find his price.
110*.9=99
Donatello payed $99
Finally, Michelangelo. His board was $200 with 40% off. So we need to multiply 200 by .6 to find his price. 200*.6=120
Michelangelo pay $120
Michelangelo payed the most
