Sorry bud, but those equations are not accurate. For commons, the cost of an indidual card is given by 2  * (2^x), with x being the number of cards bought, and the total cost is given by the definite integral of that expression integrated from 0 to x, with x cards bought. For rares the cost of any indiviual card is     20 * (2^x), for epics it is 2000 * (2^x) and for legends it is 20000 * (2^x). The same integral can be taken for any of these expressions to determine total cost. im disappointed in ur math skillz. 4/9 :(
