Answer:
$20 per day with a $50 fee
Step-by-step explanation:
For 1 day, the gold fee is $70. For 2 days, the gold fee is $90. This can be written as the ordered pairs (1, 70) and (2, 90).
To find the daily fee, we will find the slope between the points:
Next we will use point-slope form:
y-y₁ = m(x-x₁)
y-70 = 20(x-1)
Use the distributive property:
y-70 = 20(x)-20(1)
y-70 = 20x-20
Add 70 to each side:
y-70+70 = 20x-20+70
y = 20x+50
This means the fee is $50.
Use the attached formula.
Years = ln (200 / 100) / .034
Years = ln (2) / .034
Years = 0.69314718056 / .034
