YOU NEED TO ORDER ONE PIZZA FOR EVERY 5 STUDENTS AT THE PIZZA PARTY. IF THERE WILL BE 225 STUDENTS, HOW MANY PIZZAS DO YOU HAVE TO ORDER? Please help meee plsss

David estimated he had about 20 fish in his pond. a year later, there were about 1.5 times as many fish. the year after that, the number of fish increased by a factor of 1.5 again. the number of fish is modeled by f(x)=20(1.5)^x. create a question you could ask that could be answered only by graphing or using a logarithm.
