Emma spent $75 buying a used bicycle and $27 repairing it. Then she sold the bicycle for 40 percent more than the total amount she spent buying and repairing it.
\[\huge \text{WELCOME TO OPENSTUDY}\]
She spend 75+27=102 dollars on the bike. She sold it for 40% more meaning she sold it for the original price plus 40% of itself, so: 102 + 102*40/100 = 142.8$
