Answer:
The cost of spoon is £1.84 and therefore the cost of one knife is £5.52.
Given :
- A knife is 3 times the cost of the spoon.
- 9 spoons and 12 knives costs £82.80.
Solution :
- This question is solve by creating a linear equation and linear equations are nothing but yet another subset of "equations".
- Linear calculations that requires more than one variable can be done with the help of linear equations.
- The standard form of a linear equation in one variable is ax + b = 0.
Now let x be the cost of spoon. Than the cost knife is 3x. It is given that 9 spoons and 12 knives costs £82.80.
<h3>
Therefore the cost of 1 knife = 5.52
