the snack shop makes 3 mixes of nuts in the following proportions.
mix i: 6 lbs peanuts, 2 lbs cashews, 2 lbs pecans.
mix ii: 5 lbs peanuts, 3 lbs cashews, 2 lbs pecans.
mix iii: 3 lbs peanuts, 4 lbs cashews, 3 lbs pecans.
they received an order for 25 of mix i, 18 of mix ii, and 35 of mix iii. write the matrices a & b for which ab gives the total number of lbs of each nut required to fill the order.

Step-by-step explanation:

It is given that the snack shop makes 3 mixes of nuts in the following proportions.

Mix I: 6 lbs peanuts, 2 lbs cashews, 2 lbs pecans.

Mix II: 5 lbs peanuts, 3 lbs cashews, 2 lbs pecans.

Mix III: 3 lbs peanuts, 4 lbs cashews, 3 lbs pecans.

they received an order for 25 of mix I, 18 of mix II, and 35 of mix III.

We need to find the matrices A & B for which AB gives the total number of lbs of each nut required to fill the order.

                      Mix I             Mix II              Mix III

peanuts             6                  5                    3

cashews            2                  3                    4

pecans              2                   2                    2

The product of both matrices is

Therefore matrix AB gives the total number of lbs of each nut required to fill the order.

i believe the correct answer is b.

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.
