$6.00

Explanation:

10% of 200 is 20

20/30 = $.6666

Each parent gets $0.67 off.

$200/30 = $6.6666

$6.6666 ---> $6.67

6.67 - 0.67

= 6.00

Check:

6.00 * 30 = 180

200-180 = 20

Each parent pays an amount of £6.

Step-by-step explanation:

Cost of the hall = £200

Discount for parents = 10%

Cost of the hall for parents

= 200 - 10% of 200

= 200 - 10/100 × 200

= 200 - 10 × 2

= 200 - 20

= £180

If 30 parents share the cost equally,

Each parent has to pay

180/30

= 18/3

= 6

The cost per package depends on the weight of the package.

We know that a dependent variable is one which depends on some other variable or the value of the variable is calculated corresponding to the independent variable.

Generally we consider the values on the y-axis or the vertical axis as the dependent values because they are dependent upon the x-value or the value on the horizontal axis.

Here from the graph we may observe that the cost of the package depends on the weight of the package.
