When dilation is about the origin, as it is here in every case, the image point coordinates are the original (pre-image) coordinates multiplied by the scale factor.
1. Multiply every coordinate value by 5:
... W' = (-5, 10), X' = (-15, -5), Y' = (25, -5), Z' = (15, 10)
2. Multiply every coordinate value by 1/3:
... A' = (-2, 5), B' = (0, 5/3), C' = (1, 10/3)
3. A' = (2, 8), B' = (6, 2), C' = (2, 2)
4. The image coordinates are 5 times the original coordinates, so ...
... the scale factor of the dilation is 5.
Type A = $5.75 per pound
Type B = $4.55 per pound
1 set → 1 pound of Type A + 4 pounds of type B
1 set → 5.75 + 4(4.55)
1 set → $23.95
Number of sets = $526.90 ÷ 23.59 = 22
1 set → 1 pound of Type A
22 sets → 1 x 22 = 22 pounds of type A
Answer: 22 pounds of Type A
