Answer:
30% of $40 would be $12
Step-by-step explanation:
To figure this out you can do cross multiplication. Take 30 over 100 like a fraction (30/100) and then that equals x over 40 (x/40), x being 30% of $40. then you would multiply diagonally. 100 times X and 30 times 40 getting you to 100x = 1200 then isolate the variable so there is no numbers with it, meaning you have to divide both sides by 100. 100x divided by 100= X and 1200 divided by 100= 12. So X=12, meaning 30% of $40 is $12.
