Answer:

  • Sheet = $12
  • Blanket = $17

Step-by-step explanation:

Let the cost of a sheet be s and cost of a blanket be b

  • 2s + b = 41
  • s + 4b = 80

From the first equation we get:

  • b = 41 - 2s

Substitute in the second equation

  • s + 4*(41 - 2s) = 80
  • s + 164 - 8s =  80
  • 7s = 84
  • s = 12

Then

  • b = 41- 2*12 = 17
