Answer:
<u>£4.20</u>
Step-by-step explanation:
Let :
- cost of 1 kg banana = x
- cost of 1 kg apple = y
Equations formed :
- 4x + 3y = 7.50 [Equation 1]
- 3x + 5y = 8.10 [Equation 2]
Multiply Equation 1 by 5 and Equation 2 by 3 :
- 20x + 15y = 37.50
- 9x + 15y = 24.30
Subtract the newly formed equations :
- 11x = 13.20
- <u>x = 1.20</u>
Finding y :
- 4(1.20) + 3y = 7.50
- 4.80 + 3y = 7.50
- 3y = 2.70
- <u>y = 0.90</u>
Then :
- Cost of 1 kg banana = £1.20
- Cost of 1 kg apple = £0.90
Cost of 2 kg bananas and 2 kg of apples :
- 2(1.20) + 2(0.90)
- 2(2.10)
- <u>£4.20</u>
