(21 * 1.10) / 3 = 23.10/3 = 7.7....so each friend has to pay $ 7.70
Okay. 12 - 4 is 8. For the other question, you have to multiply the difference of that by 1/4. 8 * 1/4 is 2. The expression of (12 - 4) is four times the value of 1/4 * (12 - 8). and 2 is 1/4 the value of 8. The answers to this question are A , B, and C.
Hey yo!!!!!!!!!!!!!!!!
yes because if you add up the digits, you get 18, which is divisible by 3 and 9. that is the divisibility rule of 3 and 9.
hope this helped:)

Answer:
Step-by-step explanation:
If the jacket was discounted at 25%, that means that you get 25% off, right? What it also means is that you are still paying 75%. To get to the price of the jacket on sale, multiply the price of the jacket by 75% (as a decimal):
290(.75) = 217.50
That's the price of the jacket when it is 25% off the original price. If Arianna got an additional 10% off that price, that means she got 10% off but is still paying 90%. To get to the final price that she paid, multiply the sale price of the jacket by 90% (as a decimal):
217.50(.90) = 195.75
That's what she paid in the end for the jacket (i guess not counting tax...?)
$5. Subtract the cost of the magazine, $3, from the total cost, $28. Now you have $25 then you divide it by the amount of notebooks you have.
