Question

Mr. Toshiro manages a company that supplies a variety of domestic and imported nuts to supermarkets. He received an order for 120 bags of cashews, 310 bags of walnuts, and 60 bags of Brazil nuts. The prices per bag for each type are $29, $18, and $21, respectively.
Using what you have learned about vectors, compute the value of the order.

Answer 1

I'm not sure how you would solve this as a vector, but traditionally you can solve it by multiplying the number of the order's with the value of the product, and adding it all together

Like this: (120*29)+(310*18)+(60*21)
Perhaps @dude or @Vocaloid could show the vector approach.

Answer 2

set up one vector for the number of each bag, and another vector for the price per bag

<120,310,60> and <29,18,21>
and calculate the dot product
