A boating company has the following notice at the gate: "Children under the age of 13 are not allowed to operate a boat."

Part A: Write an inequality to show the age of children who are allowed to operate a boat. (5 points)

Part B: Describe in words how you can show the solution to this inequality on a number line. (5 points)

4

step-by-step explanation:

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.

answer: 12x^2+6x

step-by-step explanation:

6x does not equal 24x. hope it works!
