The cost of having a package delivered has a base fee of $10.80. every pound over 5 lbs cost an additional $0.41 per pound. write an equation that expresses the cost c in terms of w, the total weight in pounds of a package weighing over 5 lbs.

The required equation is .

Step-by-step explanation:

It is given that the cost of having a package delivered has a base fee of $10.80. Every pound over 5 lbs cost an additional $0.41 per pound.

Fixed cost is $10.80.

Variable cost is $0.41w, where w is the total weight in pounds of a package weighing over 5 lbs.

Total cost is the addition of fixed cost and variable cost.

Where, C is expresses the cost C in terms of w, the total weight in pounds of a package weighing over 5 lbs.

Therefore the required equation is .

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

multiply length by height. multiply the length by the height, and then double the product. work out 10 x 10 results = 100 square inches, then work out 100 x 2 = 200. the answer is 200 square inches.
