The cost of a slice of pizza is .
Further explanation:
Given:
A vendor sells soft drinks and pizza.
A customer came and buys slices of pizza and also buys soft drinks and the total cost for that customer is .
Another customer came and buys slices of pizza and also buys soft drinks and the total cost for that customer is .
The objective is to find the cost of a slice of pizza.
Consider the cost of the pizza to be dollars and the cost of soft drinks be dollars.
Given that a customer buys slices of pizza and soft drinks and this costs , so this can be written in the form of an equation as follows:
....(1)
Another customer buys slices of pizza and soft drinks and this costs , so this can be written in the form of an equation as follows:
....(2)
Now, we have to solve both the equations (1) and (2) to find the cost of pizza.
Multiply equation (1) by 4 as follows:
Label the above equation as follows:
.....(3)
Multiply equation (2) by 5 as follows:
Label the above equation as follows:
.......(4)
To find the value of subtract equation (3) from equation (4) as shown below:
Therefore, the value of is .
Thus, the cost of one slice of pizza is .
