Henry is purchasing a number of magnets. He wants some idea of how many he can buy. On a coordinate plane, the points (3, 1), (6, 2), and (12, 4) are plotted. Using equivalent ratios, which statements are true about the cost per magnet? Check all that apply. The cost of 2 magnets is $1. The cost of 9 magnets is $3. The cost of 10 magnets is $3. The cost of 4 magnets is $2. The cost of 6 magnets is $2. The cost of 3 magnets is $1.

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.
