Jalen is planning a trip to new york city his plane ticket cost 750$ and the hotel costs 125$ each night. if he want to spend no more than 1400$ how many nights can he stay?

You can solve this problem by using the equation 750+125x=1400 where x is the number of nights. 

750+125x=1400
750-750+125x=1400-750
125x=650
125x-125=650/125
x=5.2

The answer is 5.2. However, you cant sty for .2 nights so the answer is 5.

Khalid and Sue's Height together is 126 Inches. The difference is 6 inches, so therefore you subtract 6 from the total getting you 120 Inches. You do this with all of the problems for example: The first one. Sue is 72 inches and Khalid is 54. Add them together and subtract them by 6 to get your final answer. Please DO NOT quote me on this lol. This is how I read the question. I think this is right but I am not absolutely 100% sure. Hope this helps.
