Answer:

Step-by-step explanation:
Add the 2 equations together, then solve for x.

Now that we know the value of x, we can easily find y by substitution.

These are the answers

<u>Function modeling</u>
Real-life situations often require the help of mathematics to model numerically what happens when the variables involved can change. It could even be used to predict some expected outcomes from those models.
The problem states Janice receives $.40 per pound when he recycles less or equal than 99 pounds of aluminum. If x is the number of recycled pounds, then the amount of money he receives is

We also know that if he recycles more than 100 pounds of aluminum, the pay increases to $0.5 per pound. In that case, the amount of money is

This is a case where the function is defined differently depending on the conditions of the input variable x. It's called a piecewise function. The function can be written as

Note the function is not well constructed because there is a gap for x=100 where M is not defined. If we establish that for 100 pounds the payment is $0.5, then the second piece would include x=100
Answer:
5.50x+10y≤800
Step-by-step explanation:
The pull bouys are $5.50 each (5.50x)
The kickboards are $10 each (10y)
And the words "at most" mean less than or equal to
