Let's say t is the amount of time (in hours) it takes to make $125,
with that out of the way, the keyword "at least" makes it so that you can get 125 or more in t hours.
The inequality is $125<=7.25t.
Now you can use the guess and check method, for this example we'll use t=18 and t=17.
7.25(18)=$130.5
7.25(17)=$123.25

Therefore, the answer is 18, because 18 gives you a number greater than or equal to $125

7.25x > 125 because x equals amount of hours times 7.25 is greater that 125
