Hint 2 of 2
You need a total of exactly 16, so look for two shells plus four marbles.
Show solution
Approach: add the shell and marble values in each option
- A shell is worth 6 and a marble is worth 1.
- Two shells give 12, and you need 4 more to reach 16, so 4 marbles.
- The picture with two shells and four marbles totals 12 + 4 = 16.
- That is option E.
