The 10 little piggies $600 per month on groceries. This is 15% of their monthly budget. What is their monthly budget? *

600/15 which means 1% of their budget is $40 multiply this by 100 which gives you $4000

Answer : $4000

This is because 15% of 4000 is 600.

You get this by doing 0.15 * x = 600 and solving for x

I can check this by doing 4000/100= 40 * 15 = 600 .
