If one basketball cost $ 13.00 more than one soccer, how much did he pay for 12 basketballs? Reasoning and solution: To find how much he paid for 12 basketballs, we need to first know how much one basketball cost. To know how much one basketball cost, we need to know how much one soccer ball cost first. 6 soccer balls cost $240.00. Each of the 6 soccer balls costs the same so we can use the 3 elements formulas to solve the problem: divide the number of soccer balls or the number of groups, 6, into the total amount, 240, to find the amount in one group or how much each soccer ball costs: 240
