Mrs lee was given $1200 every month for the household expenses . she used 17/24 of it to buy food for the family. 5/7 of the remainder for the clothes and other expenses. She put the remainder money into the bank as savings for the family. Find the amount she put into the bank
spending 17/24 leaves 7/24
5/7 of 7/24 = 5/24
so, she has spent a total of 12/24 = 1/2 of her money
...
Remainder = 1200 - (17/24)*1200 = $350.
Bank = 350 - (5/7)*350 =
oops - dunno what I was thinking! 7+5=12, but not 17+5 !
:-(
To find the amount Mrs. Lee put into the bank, we need to calculate the remaining money after she spent for food and clothes/expenses.
1. Start with the total amount of money Mrs. Lee received every month, which is $1200.
2. Calculate the money she spent on food. She used 17/24 of the total amount for food expenses. To find this amount, multiply the total amount by 17/24:
Food expenses = $1200 * (17/24) = $850
3. Calculate the remaining amount after deducting the food expenses from the total amount:
Remaining amount = Total amount - Food expenses = $1200 - $850 = $350
4. Next, calculate the money she spent on clothes/expenses. She used 5/7 of the remaining amount for these expenses. To find this amount, multiply the remaining amount by 5/7:
Clothes/Expenses = $350 * (5/7) = $250
5. Finally, calculate the amount she put into the bank as savings. This is equal to the remaining amount after deducting the clothes/expenses:
Amount put into the bank = Remaining amount - Clothes/Expenses = $350 - $250 = $100
Therefore, Mrs. Lee put $100 into the bank as savings for the family.
