Answers
Cost of 500g of strawberries = £4.10
Cost of 300g of strawberries = ⅗ of £4.10
= ⅗ × £4.10
= £2.46
Now we can work out the cost of 400g of raspberries = £7.46 - £2.46 = £5.
So 200g of raspberries cost £2.50, that is half of £5.
Cost of 200g of strawberries = ⅔ of £2.46 or ⅖ of £4.10 = £1.64.
So total cost of 200 g of raspberries and 200 g of strawberries = £1.64 + £2.50 = £4.14.
Answer:
500g of strawbarries=£4.10
1g of strawbarries= £4.10÷500
=£0.0082
now 300g of strawbarries=£0.0082×300
=£2.46
cost of 400g raspberries= total cost-cost of 300g strawberries.
= £7.46-2.46
=£5
now
cost of 1g of raspberries= £5÷400
=£0.0125
cost of 200g of raspberries= 0.0125×200
= £2.5
now ,cost of 200g of strawberries = £0.0082×200
= £1.64
