if you spend 4/7 of your money and have $15 left how much did you spend

about $8.57

(multiply 4/7 and 15)

15 divided by 7=? your answer times 4 is 4/7 of 15

i don't have a calculator rn so i and put the actual answer

so you would have 3/7 of your money left

(3/7)x = 15
3x= 105
x = 35

so you spent 4/7 of that which $20

check:
you started with $35
spent 4/7 of that which is $20, leaving you with $15, as stated

To find out how much you spent, we can set up the following equation using the given information:

Amount spent = (4/7) * Total money

Since we know that you have $15 left, we can deduce that the amount spent must be the difference between the total money and $15. Let's substitute this into the equation:

(4/7) * Total money = Total money - $15

To solve for Total money, we can multiply both sides of the equation by 7 to get rid of the fraction:

4 * Total money = 7 * Total money - 7 * $15

Now, combine the terms:

4 * Total money - 7 * Total money = - 7 * $15

Simplifying further:

-3 * Total money = -7 * $15

Now, divide both sides of the equation by -3 to solve for Total money:

Total money = (-7 * $15) / -3

Calculating further:

Total money = $35

Since we know the total money, we can calculate the amount spent by multiplying it by the fraction:

Amount spent = (4/7) * $35

Calculating further:

Amount spent = $20

Therefore, you spent $20 of your money.
