When melissa is born her parents invested 2,000 in a fund that paid an annual interest of 6%. How old will melissa be when the investment is worth at least $5,000?

Answers

Answer:

25 years

Step-by-step explanation:

Given data

Principal P=  $2000

Interest rate r=  6%

FInal amount A=$5,000

The simple interest formula is given as

A=P(1+rt)

substitute and solve for t

5000=2000(1+0.06*t)

5000=2000+120t

5000-2000=120t

3000=120t

t= 3000/120

t= 25 years

Hence, for a simple interest investment, she will be 25 years

Z-31=16??? I just got into the Z section in algebra and my teacher gave us a paper with no explanation plz help ty!

Answers

Answer:z=47

Step-by-step explanation:

You're doing this because if you have z-31=16 you have to + 31 to 16 which would give you 47 then that would be a one step equation

z-31=16

you would make a line between the equal sign so it is organized then plus 31 to sixteen then that would get you to 47

write the equation of the line in fully simplified slope-intercept form.

Ann and Bill share an amount of money in the ratio 7:n
Ann gets 28% of the money.
Work out the value of n​

Answers

Answer:

48

Step-by-step explanation:

The value of n will be;

⇒ n = 18

What is mean by Ratio?

A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities. And, Total quantity gives after combine as x + y.

Given that;

Ann and Bill share an amount of money in the ratio = 7 : n

And, Ann gets 28% of the money.

Now,

Since, Ann and Bill share an amount of money in the ratio = 7 : n

And, Ann gets 28% of the money.

Thus, Bill gets the money = 100 - 28%

                                        = 72%

So, The unit ratio for the Ann = 28 / 7

                                              = 4

Hence, Bill ratio will be = 72/4

                                    = 18

Thus, The ratio of an amount of money = 7 : 18

Hence, The value of n = 18.
