Given

Jeb has to pay his plumber $65 to come to his house and $40 per hour

jeb paid him $325

Find out  how many hours did the plumber work

To proof

let the number of hours  plumber work be x

Jeb has to pay his plumber $65 to come .

extra pay per hour = $40 per hour

total jeb paid = $ 325

than the equation becomes

65 + 40x = 325

now solving the equation

40x = 325 -65

40x = 260

x = 6.5 hour

6.5 hour plumber did the work.

Hence proved
