Question

anonymous anonymous 2 years ago Math Help Please!! :) Crystal earns $5.25 per hour mowing lawns. Write a rule to describe how the amount of money m earned is a function of the number of hours h spent mowing lawns. How much does Crystal earn if she works 2 hours and 15 minutes? A) m(h) = 2h + 15; $25.50 B) m(h) = h/5.25; $0.43 C) m(h) = 5.25h; $11.29 D) m(h) = 5.25h; $11.81 Mathematics

Answer 1

It should be B or D. B because in 2 hours you make $10.50 and then add 15 minutes and you get B. It could also be D because that's doing $5.25 an hour which is true it's just deleting the extra 45 minutes so it can be either B or D.
