Three pizzas and four sandwiches cost $34 three pizzas and seven sandwiches cost $41.50 write a system of equation to find the cost of one pizza

The cost of one pizza is $8

Step-by-step explanation:

From the question;

We are required to determine the cost of  one Pizza

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

probability for j is 1/4

while

a is 1/6
