Write a function rule for the table

First, notice the the number of days goes up by 1 at a time. Each time the day goes up by 1, the cost goes up by 16. You can see that because 50 - 34 = 16; 66  50 = 16, etc. The rate of change is 16.

Now look at day 1 with cost 34. Since the rate of change per day is 16, if you subtract 1 day to find day 0, the cost for day 0 is 34 - 16 = 18. That shows that 18 is the fixed fee. The fixed fee is the y-intercept. The rate of change is the slope.

y = mx + b

The function is:

c = 16d + 18

Answer: c = 16d + 18

Each time Kristine gets paid, she spends $20 and saves the rest. If the amount Kristine earns is represented by x and the amount
kenny6666 [7]

Answer:

A graph titled Kristine's Savings has money earned on the x-axis and money saved on the y-axis. A line goes through points (20, 0) and (25, 5).

Step-by-step explanation:

If Kristine spends $20 and saves the rest when she gets paid, the amount she saves should always be 20 less than the amount she earned.

The points (20, 0) and (25, 5) accurately represent this, where x is how much she earns and y is how much she saves.

(20, 0) represents her earning $20 and saving $0, because she spends $20 every time she gets paid.

(25, 5) represents her earning $25 and saving $5, because she spent $20.

So, the correct graph is A graph titled Kristine's Savings has money earned on the x-axis and money saved on the y-axis. A line goes through points (20, 0) and (25, 5).

What percent of 9.2 m is 2.5
Nadusha1986 [10]
To solve this, you just simply divide to get a decimal and then convert to a percentage.

2.5 divided by 9.2 is equal to approximately 0.2717.

You then multiply that by one hundred to get a percentage. So the final answer is approximately 27.17%.
