Hannah and her dad go to discovery place kids. Tickets cost $10 for her and $10 for her dad if they were to purchase a $140 family membership how many time would both Hannah and her dad need to go to make the membership the better option ?

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
