400/100=4 so 4 workers are = to 1%
72×4=288 workers are part time
400-288=112 full time workers
I think it is 350(1.2)^t because you take the starting amount (350) and then multiple it by the growth rate (which is 20%, but when added to 100 and the put into a decimal is 1.2) raised by the number of hours (t).
I hope this helps.
