Answer:

-9,0

Step-by-step explanation:

Counterclockwise in math most likely relates to something being negative mean while clockwise most likely relates to something being positive. So if were making a 90 degree turn counterclockwise(negative) then all we need to do is flip the x and y cordinants and make them negative to put it simply.

The book is $10. Minus the 35% discount ($10X0.35=$3.50). So the subtotal is $10-$3.50=$6.50.

Tax is 6%. So 0.06X$6.50=$0.39

The total including tax is $6.50+$0.39=$6.89
