Explanation:
To calculate the cost of a 3-topping pizza, you'll need to add the base cost of the cheese pizza to the cost of the three additional toppings.
Base cost of cheese pizza = $7.95
Cost of each topping = $1.25
Number of toppings = 3
Now, calculate the cost of the 3-topping pizza:
Cost of 3 toppings = 3 * $1.25 = $3.75
Now, add the cost of the toppings to the base cost of the cheese pizza:
Total cost of 3-topping pizza = Base cost + Cost of toppings
Total cost = $7.95 + $3.75 = $11.70
So, a 3-topping pizza costs $11.70.
