Answer:
30 mushrooms
Step-by-step explanation:
First to solve we need to find out how many Robin found. If Bob found 12, and Robin found 6 more than Bob, we have to add 6 to 12 to find the amount Robin found. 6+12= 18. So now we know that Bob found 12, and Robin found 18. To find the total amount of mushrooms they found together, we just add how many Bob found in total, and how many Robin found in total.
12+18= 30
So they found 30 mushrooms in total.
