The answer is “x”. “x” represents the missing number in the problem.
Example:
16+x=20
The missing number, 4, would be represented as x. Hope this helps!
In this problem you would set these two equations equal to each other.
$8+ $1.50x = $10+ $1x
After this you would simplify the equation to isolate x (being the number of toppings you put on the pizzas)
$8+ 1.50x =$10+ 1x
-8 -8
----------------------------
$1.50x = $2 + $1x
-1x -1x
---------------------------
$.50x/.50 = $2/.50
_______________
x= 4 toppings and the pizzas would equal $14 total
P=15.5 would be the answer

Step-by-step explanation:
Proportions are fractions that can be made by using the given numbers, which in this case are 2, 5, 8, and 20. Let's pair each one with the other three and then simplify if possible.
First, let's begin with 2:
![\frac{2}{5} = \frac{2}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B5%7D%20%3D%20%5Cfrac%7B2%7D%7B5%7D)
![\frac{2}{8} = \frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B8%7D%20%3D%20%5Cfrac%7B1%7D%7B4%7D)
![\frac{2}{20} = \frac{1}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B20%7D%20%3D%20%5Cfrac%7B1%7D%7B10%7D)
Then, let's do 5:
![\frac{5}{2} = \frac{5}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B2%7D%20%3D%20%5Cfrac%7B5%7D%7B2%7D)
![\frac{5}{8} = \frac{5}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B8%7D%20%3D%20%5Cfrac%7B5%7D%7B8%7D)
![\frac{5}{20} = \frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B20%7D%20%3D%20%5Cfrac%7B1%7D%7B4%7D)
Note that we already have
, so we do not need to include an additional one.
Now, let us do 8:
![\frac{8}{2} = \frac{4}{1}](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B2%7D%20%3D%20%5Cfrac%7B4%7D%7B1%7D)
![\frac{8}{5} = \frac{8}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B5%7D%20%3D%20%5Cfrac%7B8%7D%7B5%7D)
![\frac{8}{20} = \frac{2}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B20%7D%20%3D%20%5Cfrac%7B2%7D%7B5%7D)
See how we already have
, so we won't have to include that as well.
Finally, let's do 20:
![\frac{20}{2} = \frac{10}{1}](https://tex.z-dn.net/?f=%5Cfrac%7B20%7D%7B2%7D%20%3D%20%5Cfrac%7B10%7D%7B1%7D)
![\frac{20}{5} = \frac{4}{1}](https://tex.z-dn.net/?f=%5Cfrac%7B20%7D%7B5%7D%20%3D%20%5Cfrac%7B4%7D%7B1%7D)
![\frac{20}{8} = \frac{5}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B20%7D%7B8%7D%20%3D%20%5Cfrac%7B5%7D%7B2%7D)
Now see that we already have both
and
, so we won't have to include both of them, as they are both extras.
Hence, the answers are
and
.
