Answer:
( $2,525 - $1,525)x = $9,000
Step-by-step explanation:
Data provided:
Salary earned by Mrs. Fuentes = $60,000
Salary earned by Ms. Williams = $51,000
Increase in salary of Mrs Fuentes = $1,525 per year
Increase in salary of Ms Williams = $2,525 per year
since, x is the number of years after which their salary will be equal
Now,
Total salary of Mrs. Fuentes after x years = $60,000 + $1,525x
and,
Total salary of Ms. Williams after x years = $51,000 + $2,525x
also,
when their salaries are equal
$60,000 + $1,525x = $51,000 + $2,525x
or
$2,525x - $1,525x = $60,000 - $51,000
or
( $2,525 - $1,525)x = $9,000
