10. Suppose you earn $7.25 per hour working part-time for a florist. What is the minimum number of hours you must work to earn a

UNO [17]

To make it like a simple, I'll make an equation. Let x be the number of hours because x represents unknown and we don't know the hours. Then your per hour is $7.25 right? so it would be x7.25. You want to know how many hours you will work so you can earn $125. The equation is simple as this x7.25 = 125.
All you have to do is divide the equation by 7.25 because that's your per hour.
It will look like this, x7.25 = 125 then the answer would be 17.24 hours.
7.25 7.25
