Can you figure out the math for this group of friends?

Today's riddle reads: "Three friends have been collecting shells. Bree has twice as many as Dylan. Ashley has 11 more than Bree. Dylan has 48 shells. How many shells does Ashley have?" Well, you know Dylan has the least. He must not be very good at finding them. So, based on how many he found, how many does Bree have? Then, how many more does Ashley have? If you think you know the answer, take a guess and check to see if it's right. Afterwards, share this with all of your friends to pass it on and see if they can find it too!
