People in New York City are starting to move away from the Frozen Yogurt craze. FroYummy, a frozen yogurt store chain, has 100 employees, but has to cut down by 6 employees every month due to the slowing sales. Frozen-yo, a competitor, has 160 employees, but also has to let 10 employees go every month. After how many months will both FroYummy and Frozen-yo have the same amount of employees?
