A glassblower can produce several sets of simple glasses in about 5 hours. When the glassblower works with an apprentice, the job takes about 4 hours. How long would it take the apprentice to make the same number of sets of glasses when working alone? Working alone it would take the apprentice about how many hours?

step-by-step explanation:

c(x)= 6x + 3

step-by-step explanation:

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain
