Francesca bought 27 key chains of two different kinds to make goody bags for her birthday party. Supergirl key chains were $3 and Wonder Woman key chains were $2. She spent $73. How many key chains of each kind did she buy?

Answer 1

She bought 19 supergirl and 8 Wonder Woman keychains. Good luck on the homework

Answer 2

Answer: Supergirl = 19 and Wonder Woman = 8

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
