Janine used the calculations shown to determine how much she would spend on 245 pencils. 3,600 pencils cost 72 dollars. (StartFraction 72 dollars Over 3,600 EndFraction) (StartFraction question mark Over 1 EndFraction) What is her error? She placed the decimal point incorrectly when dividing. She placed the decimal point incorrectly when multiplying. She wrote the rate incorrectly. She did not make an error.

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 Please DO NOT quote me on this lol.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.
