Krystal and Danielle each improved their yards by planting daylilies and ivy. They bought their supplies from the same store. Krystal spent $114 on 1 daylily and 12 pots of ivy. Danielle spent $150 on 10 daylilies and 10 pots of ivy. Find the cost of each item.

Answer:

  • $9 and $6

Step-by-step explanation:

Let the cost of daylilies = d and ivy = i, then we have below equations:

  • d + 12i = 114
  • 10d + 10i = 150

Simplify the second equation:

  • d + i = 15

Subtract the second equation from the first:

  • d - d + 12i - i = 114 - 15
  • 11i = 99
  • i = 9, ivy costs $9

Now find d:

  • d = 15 - 9 = 6, daylilies cost $6
