This week, he found 165 sand dollars, 319 sea snail shells, and 24
sand dollars, 319 sea snail shells, and 24 mini conch shells. During
which week did Peter find more shells? How many more?

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

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
