•$1,000 invested at 5% for 10 years.

simple interest. compound interest

need fast ill give you

$1,628.89 this is if it is compounded once a year

Step-by-step explanation:

Using the formula A=P[1+(r/n)]^(nt)

where

A=the ending amount

P=starting amount

r=interest rate

n=number of times interest is applied annually

t=time (years)

A=1000(1+(0.05/1))^(10)(1)

A=1000(1.05)^10

A=1000(1.62889)

A=1,628.89

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.
