Question

Mrs. Chip bought 2 sheets and a blanket and paid $41. Mrs. Dale bought a sheet and 4 blankets and paid $80.

Answer 1

• Sheet = $12
• Blanket = $17

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
