Decimal Task Card# 27 Renee makes $8.50 an hour
rolling sushi at a restaurant.
Her paycheck shows that she
worked 25.88 hours over the
past two weeks. How much did
Renee make before taxes?

the equation is not included but the answer is (1.50, 2.00, 2.75)

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
