Suppose you earn $7.25 per hour working part-time for a florist. Write and solve an inequality to find how many full hours you must work to earn at least $125.



Answer :

[tex]h-number\ of\ the\ full\ hours\\\\7.25h\geq125\ \ \ \ \ |divide\ both\ sides\ by\ 7.25\\\\h\geq\frac{125}{7.25}\\\\h\geq\frac{12500}{725}\\\\h\geq\frac{500}{29}\\\\h\geq17\frac{7}{29}\\\\Answer:You\ must\ work\ at\ least\ 18\ hours.[/tex]

7.25x >$124.99, where x equals the number of hours you work. Divide both sides by 7.25 to get 17.24 hours. This rounds up to 18 because it must be above 17.24 and a whole number. So the answer is 18 hours.
Hope this helps!
