.
(1)  d + c <= 20.              ("You can work at most 20 hours")

(2)  7.5*d + 6*c >= 92.        ("Your dog walking job pays $7.50 per hour and your job as a car wash attendant pays $6 per hour.") + 

                               ("You need to earn at least $92 to cover your weekly expenses.")

That is all.

That is what the condition says.

And it does not say anymore else.
