Question

Andrea had 32 problems to do for mathematics homework over the weekend. She did 1/4 of the problems on Friday night, and on Saturday she did 1/4 of the problems that were left to do. What was the total number of problems that Andrea needed to do on Saturday in order to complete her mathematics homework?
