Roy already has 10,368 frequent flyer miles, and he will earn 2,832 more miles from his round-trip flight to new york city. in addition, he earns 2 frequent flyer miles for each dollar he charges on his credit card. how many dollars will roy need to charge on his credit card to have a total of 15,000 frequent flyer miles? explain and determined your answer.

find his total number of miles: 10,368 + 2,832 = 13,200

subtract from 15000 to see how many more he needs: 15,000 - 13,200 = 1,800

divide by 2 to find the number of dollars: 1800/2 = 900

he'll need to charge $900 to get 15,000 miles.

b or 2, just plug these equations into your graphing calculator then check the graph to see the image. if it matches up then that's your answer!

i'm pretty sure it's 477,585,296, but perhaps my math is incorrect.
