Say you have 50k and you spend 73% of it how much do you have left
Vadim26 [7]

50k is the same as 50,000

73% = 73/100 = 0.73

Multiply 50,000 with 0.73

50,000 x 0.73 = 36500

You spend $36500.

Subtract 36500 from the total

50,000 - 36,500 = $13,500

$13,500 is the amount of money you have left.

hope this helps
