Question

Rafiq starts his job with a salary of rs 80,000 per year. he earns an increment of rs 5,000 every year. if his yearly salary after x years is rs y , then show the equation that correctly relates x and y.

Answer 1

Salary at the beginning = 80000

Increment after 1 year = 5000
Salary after 1 year = 80000 + 5000

Increment after x years = x * 5000 = 5000x
Salary after x years is y
So, y = 80000 + 5000x
