Question

QUICK:

Donald solved 5 morr MATHCOUNTS problems than Janet. Janet solved 3 more than Ann. Ann solved twice as many as Randy. If Randy solved 7 problems, how many problems did Donald solve?

(3-5 sentence explanation of how you got your answer in steps)

Answer 1

Here's how I like to represent this:

Randy = 7

Randy * 2 = Ann

Ann + 3 = Janet

Janet + 5 = Donald

If we go along and fill in the blanks for each equation, we do this:

7 * 2 = 14

14 + 3 = 17

17 + 5 = 22

So Donald solved 22 problems.

Hope this helps!
