Answer: 210 percent increase
Step-by-step explanation: So w know the starting value is k so we can replace it with 1 dollar
now we know he bought the dresser for 1 dollar and sold it for 3.10 dollars
First we have to subtract the starting value 3.1 - the original value
3.1 - 1 = 2.1
then we have to divide that number by the starting value
2.1 divided by 1 = 2.1
Lastly multiply times 100 to get the percent increase
2.1 x 100 = 210 % increase
