Spira spent 30% of her money on a pair of shoes and 20% of the remainder on a wallet. she had $56 left. how much did she have at first

The amount that she had started with was $87.36, because $56 x .20 (20%) = $11.20. So you take that amount and add it it the original $56 to get $67.20, then you multiply that new amount by .3 (30%) to get $20.16, which you then add back to the $67.20 to get $87.36. Hope I helped.
