Can someone teach me how to do these? 1. Calculate the simple interest for the following: (10mks) (I = Prt)

a. $600 at 11%/year for 6 years

b. $3000 at 15%/year for 6 months

c. $500 at 12%/year for 100 days

d. $400 at 3%/month for 15 months

e. $700 at 18%/year for 22 months

answer:

c. the third graph

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.

the clb she uses is a driver, so its a 2/5 chance she hits a 180-189 yard shot
