Answer:
15 red and 10 clear
Step-by-step explanation:
let r represent red vases and c represent clear vases, then
r + c = 25 → (1)
4.2r + 5.7c = 120 → (2)
Multiply (1) by - 4.2 and add to (2) to eliminate r
- 4.2r - 4.2c = - 105 → (3)
Add (2) and (3) term by term
1.5c = 15 ( divide both sides by 1.5 )
c = 10
Substitute c = 10 into either of the 2 equations and solve for r
Substituting c = 10 in (1)
r + 10 = 25 ( subtract 10 from both sides )
r = 15
Thus 15 red vases and 10 clear vases were bought.
