the interest earned on an account varies directly with the balance in the account. if an account with a balance of $200 earns $1
liq [111]

Answer:

\$31.25

Step-by-step explanation:

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

Let

y-------> the interest earned on an account

x------>  the balance in the account

step 1

Find the constant k of proportionality

For x=\$200,y=\$12.50

k=y/x

substitute the values

k=12.50/200=0.0625

The equation is

y=0.0625x

step 2

Find the amount of interest earned on an account with a balance of $500

so

For  x=\$500 substitute in the equation and solve for y

y=0.0625(500)=\$31.25
