Please help! i will give u medals for this and others Write a word problem that can be solved by working backward. Include at least two steps in the problem. Then, show the answer and how the problem can be solved by working backward.
you have some money in your pocket. you spend half on lunch and then a quarter of what you have left on a beer. you are left with $1.50 how much did you have to start with?
lets make it nicer and say you have some money in your pocket. you spend half on lunch and then a quarter of what you have left on a ice cream. you are left with $1.50. how much did you have to start with?
since you spent one quarter of your money on ice cream that means you have 3/4 of your money left. and $1.50 is 3/4 of $2. so you know you had $2 before you bought the ice cream. since that is half of the money you had originally, you started with $4.
if these prices seem very low, say you ended with $6 and $6 is 3/4 of $8 so you had $16 to start with, spent $8 on lunch leaving you with $8 and then a quarter of that ($2) on ice cream
