In this question, you would first need to add together Martha's stamp collection with her Sister's stamp collection to get the total. Once you have this total then you would divide by 8 in order to calculate the total number of pages (x) that you would need to completely use all of the stamps. This is calculated like so...
(154 + 248) / 8 = x
402 / 8 = x
50.25 = x
Based on these calculations you would need 50.25 pages but since you cannot have 0.25 of a page we need to round this up to the nearest whole page which would make the total number of pages needed 51 pages
You subtract the initial fee from the total cost (175.11-15.99=159.12) the you divide that by the cost of every mile and it gives you the amount of miles.
