Krystal and Danielle each improved their yards by planting daylilies and ivy. They bought their supplies from the same store. Kr
Eddi Din [679]

Answer:

  • $9 and $6

Step-by-step explanation:

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

  • d + 12i = 114
  • 10d + 10i = 150

<u>Simplify the second equation:</u>

  • d + i = 15

<u>Subtract the second equation from the first:</u>

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

<u>Now find d:</u>

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