Answer:
$4.00
Step-by-step explanation:
Mark down it by 25% three times will be 75%, so when you multiply the two, it becomes 75%. do 16/4 to get the reduction for 25%,, and you get 12. Then dive it by for 2 more times to get $4
66/25 as a decimal would be 2.64.
3,2,-5,-7 that is the order it should be in
90º (-270º): (x,y) ---> (y, -x)
180º (-180º): (x, y) ---> (-x, -y)
270º (-90º): (x,y) ---> (-y, x)
