Best ResponseYou've already chosen the best response.1the expression for how much money it costs is 1+1.75t where t is time in hours. If the cost has to be less than or equal to 7, set the expression less than or equal to 7 1+1.75t<=7 subtract 1 from both sides and divide by 1.75 this will tell you how many hours you can have remember to round down to the nearest integer

Best ResponseYou've already chosen the best response.1@hitten101 i think we both made a mistake...shouldnt it be 1+1.75(t1)<=7 because if you plug in 1 hour into the original, you get charged 2.75 not 1.00

Best ResponseYou've already chosen the best response.1no. using the new equation (the old one was wrong...sorry about that) you get t<=4.42 so it should be 4. ill check by taking 1 for the first hour, adding 1.75 for the second hour (total = 2.75) add 1.75 for the third hour (total = 4.5) and 1.75 for the 4th hour (total = 6.25) since you cant go over 7, the hours = 4

Best ResponseYou've already chosen the best response.0No @etemplin the time can go in fractions also. it does not need to be a natural number. it can be a fraction.

Best ResponseYou've already chosen the best response.1it says if you only use a partial hour it counts for a whole one

Best ResponseYou've already chosen the best response.0\[1+\text{Floor}\left[\frac{71}{1.75}\right]=4 \text{ hours}\]Floor[x] gives the greatest integer less than or equal to x.
