toni bought an old bike for 50$. She fixed it up and sold it for $80. What percent of the original value was toni’s sale price

ikadub [295]

For this case what you must do is the following rule of three:
50 ---> 100
80 ----> x
We clear x:
x = (80/50) * (100)
x = 160%
160-100 = 60%
Answer:
toni added 60% of the original value for his sale price
