susan has $450. she uses 30% of her money to but a dress and 20% of the remainder to buy a pair of shoes. how much money does she have left?
i got $225.00 left. am i right
I got a different answer.
450 * 0.3 = 135
450 - 135 = 315
315 * 0.8 = 252
Yeah Thats Correct
To find out how much money Susan has left, we need to follow the steps given in the question.
1. Susan starts with $450.
2. She uses 30% of her money to buy a dress. To find this amount, we calculate 30% of $450: 0.30 * $450 = $135.
3. After purchasing the dress, Susan has $450 - $135 = $315 remaining.
4. Susan then uses 20% of the remainder to buy a pair of shoes. To find this amount, we calculate 20% of $315: 0.20 * $315 = $63.
5. After purchasing the shoes, Susan has $315 - $63 = $252 remaining.
Therefore, Susan has $252 left, not $225 as you mentioned.
