Well in this problem we just have to work backwards doing everything opposite of what she did in order to get the final answer. so she has 39 stamps at this moment. and since she bought nine more stamps lets subtract that value to see what she had before that. 1.) 39 - 9 = 30 now she has 30. but she said that before step one she sold half of them to buy that video game. so she divided her starting number by two. so again we are going to work backwards by multiplying the number by 2:) 2.) 30 x 2 = 60!! 3.) So she started out with 60 stamps answer is 60:) hope i helped
Well it is a simple percentage question that we have to solve.
As we know that William made 620 by baby sitting and we also know that he made 340 per cent more next year so we can simply calculate 340 per cent of 620 and then add that percentage value to 620 to calculate the final answer.
So 340 / 100 * 620 equals to 2108 so the final answer is 2108 + 620 which becomes 2728.
