James wants to be able to make a $30,000 down payment on a new home in three years. if he can invest his savings in an account that earns 6%
interest per year, compounded monthly, about how much will james need to deposit today to achieve his goal?
a.
$25,002
o
b. $25.069
c. $25,189
od. $35,730

B. $25,069

Step-by-step explanation:

An interest of 6% per year, compounded monthly it means that he earns 6/12% = 0.5% of what he has invested every month.

If he invests x money what he will have the first month will be :

Money = x*(1+0.005)

The next month:

Money' = Money*(1+0.005) = x *(1+0.005)(1+0.005) = x* (1+0.005)^2

Therefore in this type of interest the formula is:

Money = x*(1+r)^n

Where:

x is the money invested the first time

r is the interest

n is the number of periods

For this problem:

x = what you have to find

r = 0.005

n = 3 years (1 period is 1 month) then the period is 36 months

Money = 30000

Replacing:

30000 = x * (1+0.005)^36

x = 25,069

step-by-step explanation:

fabric (square meters)                   cloaks

7                                                           21

4/3                                                         4

step-by-step explanation:

we are told that harry needs 2 square meters of fabric for every 6 wizard cloaks he makes.

1. first of all we will find how many cloaks can be made from 1 square meter of fabric by dividing 6 by 2.

we can see that 3 cloaks can be made from 1 square meter of fabric. now we will multiply 3 by 7 to find number of cloaks made from 7 square meters of fabric.

therefore, harry will make 21 cloaks from 7 square meters of fabric.

2. let us find how many square meters of fabric will be needed to make 4 cloaks.

first of all we will find fabric needed for 1 cloak by dividing 2 by 6.

we can see that fabric needed for 1 cloak is   square meter. now we will multiply   by 4 to find fabric needed for 4 cloaks.
