Question

Ay mamá mía pizza place,the price of a large pizza is determined by p=9+1.5x,where x represents the number of toppings on a pizza added to a cheese pizza Daniel spent $13.50 on a large pizza.How many toppings did he get?

Answer 1

Answer:

3

Step-by-step explanation:

The equation

p = 9 + 1.5x

gives us the price of pizza depending on toppings

Where

p is the cost of pizza

x is the number of toppings

Now, Daniel took a pizza that costed 13.50. We need to find number of toppings. We can put 13.50 into p (since this is the cost) and solve for x to find number of toppings. Shown below:

$p=9+1.5x\\13.5=9+1.5x\\13.5-9=1.5x\\4.5=1.5x\\x=\frac{4.5}{1.5}\\x=3$

So, Daniel got 3 toppings
