A notebook costs 4 times more than a pencil. The pencil is 30gh less than the note book . What is the price of the pencil
N = 4P
N - P = 30
Substitute 4P for N in the second equation and solve for P.
Let's assume the price of the pencil is P gh.
According to the given information, the notebook costs 4 times more than the pencil. So, the price of the notebook is 4P gh.
It is also mentioned that the pencil is 30gh less than the notebook. So, we can set up the equation:
4P - P = 30
Simplifying the equation, we have:
3P = 30
Dividing both sides of the equation by 3:
P = 10
Therefore, the price of the pencil is 10gh.
To find the price of the pencil, we can use the given information and set up an equation.
Let's assume the price of the pencil is 'x' Ghanaian cedis.
According to the given information, the notebook costs 4 times more than the pencil. So, the price of the notebook would be 4x Ghanaian cedis.
It is also mentioned that the pencil is 30 Ghanaian cedis less than the notebook. So we can set up the following equation:
4x = x + 30
To solve this equation, we can rearrange it by subtracting 'x' from both sides:
4x - x = 30
3x = 30
Divide both sides of the equation by 3:
3x/3 = 30/3
x = 10
Therefore, the price of the pencil is 10 Ghanaian cedis.
