Answer:

Step-by-step explanation:

Common examples of "unit rate" follow:

miles per hour (mph).  How many miles are covered in 1 hour of driving?

25 cents/pen:  each pen costs 25 cents each.

Suppose I know I can pack 1/4 box in 20 minutes.  How many boxes can I pack in 1 hour?  That would be a unit rate.  To find it, write out the ratio

1/4 box                                                                                 60 min

-------------   and multiply this by the conversion factor    ---------------

 20 min                                                                                  1 hour

... which results in  3/4 box per hour (a unit rate)

If the Ramirez family deposits $5000 in a savings account at 7.5% interest compounded continuously, how much will be in the acco
GenaCL600 [577]

Answer: The amount is $14794.39 and the interest is $9794.39

Step-by-step explanation: If you deposit <em><u>$5000</u></em><u> </u>into an account paying <em><u>7.5%</u></em> annual interest compounded yearly , how much money will be in the account after <em><u>15 years</u></em>?

To find amount we use formula:

A-P(1+r/n) n*t

A = total amount

P = principal or amount of money deposited,

r = annual interest rate

n = number of times compounded per year

t = time in years

P=$5000, r=7.5, n=1 and, t=15 years

After plugging the given information we have

A= $5000 (1+0.075/1)^1.15

A= 5000 *1.075^15

A=14794.39

To find interest we use formula  A=P+I'

since A= 14794.39  and P=5000

we have: A=P+I 14794.39=5000+I

I= 14794.39 -5000

I=9794.39
