Answer:
5 kg
Step-by-step explanation:
To solve this problem, we can use the rule of three.
In fact, we know that:
- 1 kilogram is equivalent to 2.2 pounds
- The ratio between the mass in kilograms and in pounds is constant for every value of the mass
- Therefore, the mass in kilograms corresponding to 11 pounds can be found by writing the following equation:

Where
x is the mass in kilograms corresponding to 11 pounds.
Solving the equation for x, we find:

The toppings would still cost 0.50 each (since it is just toppings)
The large pizza costs $18 if you do not have any toppings
The medium costs half of the large
18/2 = 9
The medium costs $9 without any toppings, so your new equation will be:
c = 0.50t + 9
