The population of rabbits at a lab doubles every year.
The lab was started initially with 7 rabbits. Your program needs to calculate the number of rabbits you will have after the number of years provided as input.
Review the loops lesson just prior to this practice. Start with 7 rabbits. You need to loop years times (get years as an input). Inside the loop double the amount of rabbits (rabbits = rabbits * 2) and set the new amount back to the rabbits variable. After the loop output the amount of rabbits.
