Answer:
The cost of one pizza is $8
Step-by-step explanation:
From the question;
- 3 pizzas + 4 sandwiches = $34
- 3 pizzas + 7 sandwiches = $41.50
We are required to determine the cost of one Pizza
- Assuming the cost of one pizza is x and the cost of one sandwich is y
Then we get the equations;
3x + 4y = $34
3x + 7y = $41.50
We can solve the equations simultaneously;
Subtracting the two equations;
3x + 4y = $34
3x + 7y = $41.50
...........................................
-3y = -$7.5
y = $2.5
To get x;
3x = $34 - 4($2.5)
3x = $24
x = $8
Therefore, the cost of one pizza is $8
