Answer:
945 dollars
Explanation:
We don't even need to glance at the graph to sovle this, for the question doesnt ask about crew C, only crew B. Lets just look at what theys say below.
So in 3 hours, this crew made 315 dollars? Lets not even look at the 5 hours and dollars, we don't need to.
First, lets divide the dollars by the hours. This will show you the dolllars per hour:
315/3
=
105
Well, 3 goes into 15, 5 times. 3 goes into 3 only 1 time, but lets add 2 zeros to that, now you have 100 and 5. Add the two together, you get 105.
So now we know that crew B makes 105 dollars per hour.
The question asks for how much the crew makes in 9 hours.
So all we have to do is multiply the dollars per hour by 9 hours to get our answer:
9x105
=
945
Well, 9 times 5 equals 45. And 1 times 9 is 9, lets just add two zeros behind that, because its in the h8undreds, and you get 900 and 45. Getting you 945.
Now wer know that the amount of money that crew B makes in 9 hours is:
945 dollars.
Hope this helps!
