Question

Deion and Brian already had 8 shells in their shell collection. Then they went to the beach to collect even more. Deion found 9 limpet shells, 10 oyster shells, and 2 conch shells. Brian found 18 more shells than Deion did. How many shells do the pair have altogether?

A. 37
B. 46
C. 55
D. 64

Answer 1

Deion found 21 shells and Brian found 39 shells. Therefore, the pair has 60 shells altogether.

Step-by-step explanation:

To find the total number of shells collected by Deion and Brian, we need to add up the number of shells each of them found.

Deion found 9 limpet shells, 10 oyster shells, and 2 conch shells. So, the total number of shells Deion found is 9 + 10 + 2 = 21 shells.

Brian found 18 more shells than Deion did. Therefore, Brian found 21 + 18 = 39 shells.

To find the total number of shells collected by Deion and Brian altogether, we add their individual shell counts: 21 + 39 = 60 shells.

Therefore, the pair has 60 shells altogether.
