A student spends one-third of her money on a pair of running shoes. She spends one-quarter of the money she has left on a sweatshirt and then has $128.99. How much did she start with?

Answer 1

3/4 x 2M/3 = 128.99

M= $257.98= the money she started with

she spent 1/3 leaving 2/3

she spent 1/4 of 2/3 leaving 3/4 of 2/3 = 3/4x2/3 = 1/2

128.99 is 1/2 her original amount

2x 128.99 = $257.98

she spent 1/3 of 257.98 = 257.98/3= $85.99

leaving 257.98-85.99 = $171.99

she spent 1/4 of 171.99 = $43

leaving 171.99-43 = $128.99
