Melissa puts 2/5 of her babysitting money in savings and uses 1/2 of the remaining money to go to the movies. If she has $12 left, how much did she have at first?
If you work backwards, she had 24 before going to the movies. This is 3/5 of what she had originally. Use this to find 1/5 the but dividing 24 by 4 = 8 then multiply by 5 to get back to the original value 8 x 5 = 40
1/2 for the movies the other 1/2 is the $12 12×2=24 $24 is 3/5 of her babysitting money 24/3=8 $8 is 1/5 of her babysitting money 8×5=40 Solution: She had $40 at first
