Question

Nadia makes a monthly income of $4,000. How much will Nadia have for impulse shopping after she pays all of her bills for the month? Food: 15% Housing: 26% Transportation: 3% Insurance: 20%

Answer 1

You add all the percentages up and it will give you 64. take 64 and put it over 100 because percentages as a fraction will always be the amount over a 100.  
so its 64/100 multiply by 4000/1. 64*4000= 256000 over 100. 256000 divided by 100 = 2560

$2560
