A tiger in a zoo has consumed 120 pounds of food in 10 days. If the tiger keeps consuming food at its current rate, how many more days will it take for its overall food intake to reach 168 pounds?
If the tiger has consumed 120 pounds of food in 10 days that's 120/10 = 12 pounds of food per day. The tiger needs to consume 168 - 120 = 48 more pounds of food to reach 168 pounds total. At 12 pounds of food per day, that's 48/12 = 4 more days.
