John is going to start saving $20 every month to buy a new IPod. His parents gave him $10 for his birthday to open his savings account. The equation y = 20x + 10 represents John’s savings account balance x months after be began saving.


a) How many months will it take John to save enough money for the $300 IPod? Explain.


b) If John saved $40 per month instead of $20, how would you expect the slope of the graph to change? Explain.

Answer:

A) It will take john 15 months to save./////B)The slope of the graph would be steeper.

Step-by-step explanation:

A) It will take him 15 months because 300/20 is 15 and if he earns 20$ every month you multiply 15 by 20 and get 300$.So he will earn 300$ for the new Ipod in 15 months.

B)The slope would be steeper because he is earning more money in less of a time.In this case he would earn 300$ in 7 1/2 months.

Answer A: It would take fifteen months, or one year and three months, to get three hundred dollars.

Answer B: It would take seven and a half months to get three hundred dollars at this rate. It would also change the slope by making it go down more.

Step-by-step explanation:

Three hundred divided by twenty equals fifteen, which represents the amount of months.

If you do the same thing with the other ratio, but change twenty to forty, you get seven and a half.

Have a nice day!
