WEST LAFAYETTE, Ind. (WOWO): Purdue has conducted a study on raising the minimum wage for fast food workers.

They found that, if wages were to be increased to $15 per hour for fast-food employees, it would lead to an estimated 4.3 percent increase in prices at those restaurants. 

The study comes after fast-food workers across the nation have gone on strike in the last two years, calling for wages to be increased from the standard $7.25 an hour to $15 per hour.
