Question

4 knives and 5 forks cost £4.90 in total. 7 knives and 3 forks cost £5.70 in total. How much do they each cost?

Answer 1

Each knive costs £0.60 and each fork costs £0.5

Explanation:

Let's recall knives' price as `x` and forks' price as `y`.
Then we get these 2 equations:
`4x+5y=4.90`
`7x+3y=5.70`

There are plenty of ways to solve this, choose which you like the most.

Finally we get:
`x=0.6`
`y=0.5`
