Hi! Im having some trouble with a math question: "Mary rents a room for her graduation party. There is a flat fee plus a charge per hour. Based on the graph shown below, what are the flat fee and hourly rate?" The graph has ratios, ( Hours: Cost ) 0; 40, 1; 45.25, 2; 50.5, 4; 61, and 6; 71.5. The answer choices are ( all in dollars ) A: 40; 45.25 | B: 45.25; 4.13 | C: 45.25; 5.25 | D: 40; 5.25

$40; $45.25

Step-by-step explanation:

So if you know look at the question it says 1;$45.25 which means in 1 hour you pay $45.25 and then it also says 0;$40 which means the flat fee is $40 and the hourly rate is $45.25
