Answer:
Cost = [tex]\frac{7x}{2}[/tex]
Step-by-step explanation:
Let the number of pizza purchased by Mario = x
Cost of one pizza = $7
Total cost of x pizza = Number of pizza × Cost of one pizza
= $7(x)
If the cost of will be split between Mario and his brother, expression representing the cost by them individually,
Cost = [tex]\frac{7x}{2}[/tex]
Therefore, Cost = $[tex]\frac{7x}{2}[/tex] will be the answer.
