450 divided by 2 is 225. 225-50=175. 225+50=275
John has 275 and Andrew has 175.
In order to get this answer, first you divide the whole number by 2. Then you get the number 225. You then have to subtract 50 from 225 because John gets 50 more than Andrew. Then for John, you have to add 50 to 225. To self-check the answer, here is the formula: 175+275=450. Remember that on these kind of word problems, you first divide the whole. Then subtract and add the number that one person gets more than the other person.

Answer:
Step-by-step explanation:
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form 
or 
Let
y-------> the interest earned on an account
x------> the balance in the account
step 1
Find the constant k of proportionality
For 
substitute the values
The equation is
step 2
Find the amount of interest earned on an account with a balance of $500
so
For 
substitute in the equation and solve for y
