Martina went shopping. She spent a fifth of what she had in her wallet and then a fifth of what remained. In all, she spent $36. How much did she start with?

x is th amount she starts with in her wallet.

she spends 1/5 of x 1/5 x so now she has 4/5x LEFT

of what she has LEFT , she spends 1/5

1/5 * 4/5x

so all totalled she spent 1/5x + 1/5 * 4/5 x =36

1/5x + 4/25x =36

5/25 x + 4/25 x = 36

9/25 x = 36

x =36 (25/9) = original amount = $100.
