Craig has a box of chocolates to share when his friends. the box has 5 rows of chocolate with 20 chocolates in row. craig and his friends eat 64 chocolates. how much did they eat? show this as an decimal.

0.64

Step-by-step explanation:

Given: Craig has a box of chocolate with 5 rows in it.

           Each row has 20 chocolate.

           Craig and his friends eat 64 chocolate.

As given, we understand that there is box of chocolate with 5 rows and each row have 20 chocolate, therefore we can find total number of chocolate.

Total number of chocolate=

∴ Total number of chocolates in box= 100.

Now, we know craig and his friends eat 64 chocolate.

∴ To find decimal of number chocolate eaten out of 100 chocolate, we need to  put numbers in fraction first then convert it in decimal.

Number of chocolate ate by craig and his friends is

∴ Craig and his friends eat 0.64 chocolates.

step-by-step explanation:

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
