42.5p=c
You get you get the number 42.5 since you know 10 people paid 425, you would divide 425 by 10 to know how much every person paid.
M is representing the amount of money each person paid
(M)10=425
M=425/10
M=42.50 <- since it’s about money
Each person paid $42.50
The cost for 15 people is $637.50.
42.5p=c
42.5(15)=637.5
x = 37.5 (or) 
Solution:
Given 
AC = 50, DE = 30, EC = 25, BE = x, BC = 25 + x
To find the value of x:
Property of similar triangles:
If two triangles are similar then the corresponding angles are congruent and the corresponding sides are in proportion.


Do cross multiplication, we get


Subtract 30x from both sides of the equation.

Divide by 20 on both sides of the equation, we get
x = 37.5 (or) 
Hence the value of x is 37.5 or
.
