Two bags of crisps and five chocolate biscuits cost £1.76.If each bag of crisps costs 4p more than a chocolate biscuit,
what is the cost of a biscuit?
To find the cost of a biscuit, we can set up a system of equations based on the given information.
Let's assume the cost of a chocolate biscuit is "x" pence.
According to the information given, each bag of crisps costs 4p more than a chocolate biscuit. So, the cost of a bag of crisps would be "x + 4" pence.
Now, we know that two bags of crisps and five chocolate biscuits together cost £1.76, or 176 pence.
So, we can set up the equation:
2 * (x + 4) + 5 * x = 176
Now, let's solve this equation to find the value of "x", which represents the cost of a chocolate biscuit.
2x + 8 + 5x = 176
Combining like terms:
7x + 8 = 176
Subtracting 8 from both sides:
7x = 168
Dividing both sides by 7:
x = 24
Therefore, the cost of a biscuit is 24 pence.
cost of biscuit ---- x p
cost of crisp ------ x+4 p
2(x+4) + 5x = 176
solve for x
