Linda saves $1.55 every day. Tyron saves $3.90 every day. Linda started saving 3 days earlier than Tyron. On which day will Tyro

madreJ [45]

Step 1: Write the amount of savings in equation
Linda's savings: s=1.55d
Tyron's savings: m=3.90d

Step 2: Add on the extra days to Linda's savings
Linda's savings s=1.55d+3(1.55)

Step 4: Simplify equation
s=1.55d+3(1.55)
s=1.55d+4.66

Step 5: Substitute numbers for d days until Tyron's m savings is greater than Linda's s saving
m=3.90d s=1.55(2)+4.66
m=3.90(2) s=3.10+4.66
m=7.80 s=7.76

On Tyron's second day he will have more money in his savings than Linda does.

An Archaeologist in Turkey discovers a spear head that contains 51% of its original amount of C-14. Find the age of the spear he

disa [49]

Use given half-life for C-14 of 5,730 years.

The exponential decay function:
$y = e^{-kt}$
plug in half life, solve for 'e^(-k)'
$0.5 = e^{-5730k} \\ \\ 0.5 = (e^{-k})^{5730} \\ \\ e^{-k} = (0.5)^{1/5730}$

Sub into original decay function, plug in 0.51 for 'y' and solve for 't'

$y = e^{-kt} = (e^{-k})^t \\ \\ 0.51 = (0.5)^{t/5730} \\ \\ ln(0.51) = \frac{t}{5730} ln(0.5) \\ \\ t = 5730 \frac{ln 0.51}{1n 0.5}$
