sand dollars, 319 sea snail shells, and 24 mini conch shells. During
which week did Peter find more shells? How many more?

Answer :

Answer:

Step-by-step explanation:

Last week: we can add together the amount of shells he collected for each type

241 + 106 + 82 = 429 shells

165 + 319 + 24 + 24 = 532 shells

532 - 429 = 103 shells

He found 103 more shells this week
