Justin gave the clerk $20 to pay a bill of $6.57 how much change should justin get?

Given that Justin gave the clerk $20 to pay a bill of $6.57.

Now we have to find how much change should justin get.

Justin will recieve change only if he paid more money that the bill amount.

Clearly $20 (paid money) is more than $6.57 (bill amount)

Hence Justin will recieve difference of both values.

To find the difference, we subtract 6.57 from 20

20-6.57= 13.43

Hence Justin will get change of $13.43

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
