C -> Umesh's total charge in dollars.
h -> the number of hours he spends on a job.

Therefore, C = 80h +50 is the required equation to find the total charges</span>
The number of subscribers y to a newspaper after t years is shown by the equation , where 75 is the initial number of subscribers to a newspaper and t is the time period is years.
