Kaya found 25 shells on the beach yesterday.Today she found 25 more shell. She sorted all the shells into 5pile.Which equation can be used to find how many shells are in each pile?A.s=(25+25)÷5B.s=25÷5C.s=(25+25)-5

the answer is A. because you want to take the two days 1 & 2  25 shells per day 25 + 25 = 50 /5 and you want to use parentheses so you get 50 BEFORE you divide it by 5 so it would look  like this ... (25 + 25)/5
