A jewelry shop makes and sells pearl necklaces. The shop has a total of 6,832 pearls. Each necklace has 16 pearls. Marvin says that the greatest number of necklaces the jeweler can make with all of the pearls in the shop is 682. Marvin's work is shown below. Explain why Marvin's answer is incorrect and how he can find the correct answer.

I  dont know why he was incorrect because you didn't show us it but the correct answer is 427.

Step-by-step explanation:

You will divide 16 into 6,832 then you will do 16 times 4 and it will give you 64 and you subtract that and you will get 43 and then do 16 times 2 and you will get 32 and you subtract 43 and 32 then you will multiply 16 times seven and you will get 112 and subtract that by 112 and you will get zero.

11 15 15/x

Jonah spent the cost of a movie ticket and split the cost of popcorn, so this needs to be represented by a " + ". Jonah just buy one piece tickets, so 11 is tickets price. We know Jonah's costs represented by the expression 11+15/x, "x" on behalf of the number of he and his friends, so 15 is the price of popcprn. 15/x means one person's money for the poopcorn, including Jonah.
