Answer:
w=2
Step-by-step explanation:
1+w=3
-1 -1
w = 2
If B went from (1, 5) to (-3, 2), that means it was shifted down 4 units and left 3 units. So for each of the other points, we subtract 4 from the x value, and subtract 3 from the y value. Point A is (-3, -4), moving this by subtracting 4 from x and 3 from y, we get A'(-7, -7). Point C was (4, 1), subtract 4 and 3, leaving C'(0, -2).
So A'(-3, -4), B'(-3, 2) and C'(0, -2)
15 x .30 = 4.50 discount 15-4.50= 10.50
10.50 x .40 = 4.20
Final cost of shirt 10.50-4.20 = $6.30
