Answer:
The cost of a specialty pizza is $19.49.
Explanation:
To write a subtraction equation that could be used to find the cost c of a specialty pizza, we need to set up an equation that represents the relationship between the cost of a one-topping pizza and the cost of a specialty pizza.
The problem states that a one-topping pizza costs $6.50 less than a specialty pizza. Therefore, we can subtract $6.50 from the cost of a specialty pizza to get the cost of a one-topping pizza:
Cost of specialty pizza - $6.50 = Cost of one-topping pizza
We can rearrange this equation to solve for the cost of the specialty pizza:
Cost of specialty pizza = Cost of one-topping pizza + $6.50
Now, we can substitute the given value for the cost of a one-topping pizza:
Cost of specialty pizza = $12.99 + $6.50
Simplifying the expression, we get:
Cost of specialty pizza = $19.49
Therefore, the cost c of a specialty pizza is $19.49.
