Answer:
The original cost is $350
Step-by-step explanation:
Let's assume
original cost of computer is x
There is a 10% off sale on laptop computers
So, amount saved is
now, we are given
someone saves $35 on a laptop
so, we can set them equal
and then we can solve for x
we can divide both sides by 0.10
and we get
So,
The original cost is $350
Answer:
The puzzle is first add the current two numbers and then add their sum to result obtained in previous step.
Step-by-step explanation:
1 + 4 = 5
2 + 5 = 12
12 is obtained by adding 2 + 5 = 7 and adding the result obtained in previous result which is 5 to 7
⇒ 7 + 5 = 12
Now, 3 + 6 = 21
21 is obtained by first adding 3 + 6 = 9 and the previous result obtained is 12
So adding 12 to 9 ⇒ 12 + 9 = 21
Hence, The puzzle is first add the current two numbers and then add their sum to result obtained in previous step.
605,970 is expanded in this form:
(6 x 100,000) + (0 x 10,000) + (5 x 1,000) + (9 x 100) + (7 x 10) + (0 x1)
each number is multiplied to the corresponding place value.
6 is on the one hundred thousand place value
0 is on the ten thousand place value
5 is on the one thousand place value
9 is on the hundreds place value
7 is on the tens place value
0 is on the ones place value
OR
600,000 + 5,000 + 900 + 70 = 605,970
