Final answer:
To earn at least $125 while earning $7.25 per hour working as a florist, you must work a minimum of 18 full hours.
Step-by-step explanation:
To find how many full hours you must work to earn at least $125, we can set up an inequality using the given information. Let h represent the number of full hours worked. Since you earn $7.25 per hour, the inequality can be written as:
7.25h ≥ 125
To solve for h, divide both sides of the inequality by 7.25:
h ≥ 125/7.25
h ≥ 17.24
Since we are looking for a whole number of hours, you must work a minimum of 18 full hours to earn at least $125.
