Answer: Supergirl = 19 and Wonder Woman = 8

Step-by-step explanation:

Let g represent the quantity of Supergirl keychains and w represent the quantity of Wonder Woman keychains.

Qty Cost

Supergirl g $3g

Wonder Woman w $2w

Total 27 $73

Qty: g + w = 27 → -2(g + w = 27) → -2g - 2w = -54

Cost: 3g + 2w = 73 → 1(3g + 2w = 73) → 3g + 2w = 73

g = 19

Input g = 19 into one of the original equations to solve for w:

g + w = 27

(19) + w = 27

w = 8
