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.
ANSWER: $432
STEP-BY-STEP EXPLANATION:
The cost of the tablet is $360
Then Tabitha has to pay 20% sales tax.
The tax is the prices times 20% plus the original price
360 ( 1+ 0.2)
360 (1.2)
=432
You do the same as with number you take out the largest allowed amount. For example for 8 you could take out x^2 and y^2 along with the normal factors, So once you factor everything out you would be left with 27x^2y^2(y^3-3x)
