The dot product will have you multiply the corresponding coordinates and add up the products
v dot w = (6*(-7)) + (7*5) + (-3*2)
v dot w = -42 + 35 - 6
v dot w = -7 - 6
v dot w = -13
Answer: -13
The store must sell 45 bicycles each month to break even.
Step-by-step explanation:
Cost per month to operate = $2700
Average paid per bicycle = $45
Average paid of x number of bicycles = 45n
Therefore,
Total operating cost per month = 2700+45n
Average selling price of each bicycle = $105
Price of x bicycles = 105x
For breaking even;
Total operating cost = Total cost of sold bicycles

Dividing both sides by 60

The store must sell 45 bicycles each month to break even.
