Answer:

starbucks is a better by because they each sell one ounce for the same price. from starbucks you get more ounces for the same price as you would at circle k

starbucks: 24 / 336 = $0.07

1 ounce sells for about $0.07

circle k: 16 / 240 = 0.066 = (rounded) 0.07

If $48,000 is invested in an account earning 3.1% interest compounded continuously, determine how long it will

Answer:

It will take about 35.439 years to triple.

Step-by-step explanation:

Recall the formula for continuously compounded interest:

$A=P\,e^{r*t}$

where "A" is the total (accrued or future) accumulated value, "r" is the rate (in our case 0.031 which is the decimal form of 3.1%), "P" is the principal, and "t" is the time in years (our unknown).

Notice also that even that the final amount we want to get is three times $48,000. So our formula becomes:

$3\,*\,48,000=\,48,000\,\,e^{0.031\,*t}\\\frac{3\,*\,48,000}{48,000} =e^{0.031*t}\\3=e^{0.031*t}$
