The relative growth rate for a certain type of mutual fund is 15% per year. An account is opened with a balance of $3,000. How m

wlad13 [49]

We have been given that an account is opened with a balance of $3,000 and relative growth rate for a certain type of mutual fund is 15% per year.

In order to tackle this problem we have to find the value of mutual fund after 5 years. For our purpose we will use compound interest formula.

$A=P(1+r)^{t}$ ,where A= amount after t years, P= principal amount, r= interest rate (decimal) and t= number of years.

After substituting our given values in above formula we will get

$A=3000(1+.15)^{5}$

Now we will solve for A

$A=3000(1+.15)^{5}=3000(1.15)^{5}\\ A=3000\cdot (2.011357187)=6034.07$

Therefore, after 5 years mutual fund is worth $6034.07.

Find the integer that makes this subtraction statement true -3 - ? = -5

Elenna [48]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{2}}}}}$

Step-by-step explanation:

Let the missing integer be x

Solve for x

$\sf{ - 3 - x = - 5}$

Move 3 to right hand side and change it's sign

$\dashrightarrow{ \sf{ - x = - 5 + 3}}$

The negative and positive integers are always subtracted but posses the sign of the bigger integer

$\dashrightarrow{ \sf{ - x = - 2}}$

Change the signs of both sides

$\dashrightarrow{ \boxed{ \sf{x = 2}}}$

Hope I helped!

Best regards! :D
