E a real estate broker earns a salary of $21,000 plus 2.5% of the value of any real estate sold. last year the broker earned $52,000. what was the total value of all real estate sold by the broker?

Salary of real estate broker = $21,000

plus 2.5% of the value of any real estate sold = 2.5% = 0.025

last year the broker earned = $52,000

total value of real estate sold by the broker = ?

let the total value is X, so the equation will be

$21,000 + 2.5%of X = $52,000

replace 2.5% with 0.025

0.025X = $52,000 - $21,000

0.025X = $31,000

X = $31,000 / 0.025

X = $1,240,000

S the total value of real estate he sold is $1,240,000.
