D. 1,368​

D

Step-by-step explanation:

First, start with the ones column. 2*9 is 18, so write the 8 below and carry the 1 into the tens column. Now, we do 9*7 plus the 1 we carried, so that makes 64. The first row under the line should be 648. Next, annex a zero under the number 648 in the ones column. Now we move to the tens. 1*2 is 2. 1*7 is 7. The number under 648 should be 720. Now, we add 648 and 720. 648+720 is 1,368. 1,368 is our final product, which makes the answer D. I'm sorry if this seemed confusing (it's a bit hard to explain in words), but I hope it helps!

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
