Crystal earns $5.50 per hour mowing lawns. a. Write a rule to describe how the amount of money m earned is a function of the number of hours h spent mowing lawns.
b. How much does Crystal earn if she works 3 hours and 45 minutes?

m(h) = 3h + 45; $61.50

m(h) = 5.50h; $18.98

m(h) = 5.50h; $20.63

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

no because mercury has a density of 13.6 grams per centimeter squared while gold has 19.32 grams centimeter squared
