If I did my math correctly, Helen would have $463 left after her expenses.

The first step is to find how much money 45% of $1840 is. When you multiply 0.45 by 1840 I got 825. So 45% of $1840 is $840.
Then I needed to find what 1/10 of $1840 is. 1/10 is equal to 10%, or 0.1. If you multiply 0.1 by 1840 you get 184. So 1/10 of $1840 is $184. 
1/5 is equal to 20%, or 0.2. Take 0.2 and multiply it by 1840 and get 368. So, 1/5 of $1840 is $368.
I then added all three numbers, 825, 184, and 368, toghter and got 1377.
So now we know that $1377 is used to pay for Helen's expenses.
The last step is to subtract 1377 from 1840 to get the final answer of 463.
So, Helen has $463 dollars left after all her expenses.

The amount of money that Helen would have left after all these expenses is  $460.

What is the amount left?

In order to determine the amount that would be left, determine the money value of the expenses, add the expenses together and subtract it from the earnings.

  • Amount spent on rent = 45% x 1840 = $828
  • Amount spent on utilities 1/10 x 1840 = $184
  • Amount spent on food = 1/5 x 1840 = $368
  • Total value of expenses = 1380

Amount left = 1840 - 1380 = $460
