Nick bought a video game for $55, which was 20% off the original price. what was the original price?

Answers

the \ original \ price : x \n \n x\cdot 20\% = 55 \n \nx\cdot (20)/(100)=55\n \n(1)/(5)x=55 \ \ / \cdot 5\n \nx=\$ \ 275 \n \n Answer : \ the \ original \ price \ it \ \$ \ \ 275 .
Since $55 would be 80% of the original (since it was 20% off) you would divide the $55 by 4 to get 1/5 if the original price ($13.75) and multiply it by 5 to get the original price. $13.75x5=$68.75

At Silver Gym, membership is $25 per month, and personal training sessions are $30 each. At Fit Factor, membership is $65 per month, and personal training sessions are $20 each. In one month, how many personal training sessions would Sarah have to buy to make the total cost at the two gyms equal?

Answers

Sarah would have to buy 4 personal training sessions to make the total cost at the two gyms equal.

Step-by-step explanation:

Membership fee at Silver gym = $25 per month

Cost of one training session = $30

Membership fee at Fit Factor = $65 per month

Cost of one training session = $20

Let,

x be the number of training sessions in a month,

S(x) = 25 + 30x    Eqn 1

F(x) = 65 + 20x    Eqn 2

The two functions will be equal when the cost will be same, therefore,

S(x) = F(x)

25+30x=65+20x\n30x-20x=65-25\n10x=40

Dividing both sides by 10

(10x)/(10)=(40)/(10)\nx=4

Sarah would have to buy 4 personal training sessions to make the total cost at the two gyms equal.

Rename the number 9,200 hundreds. please help me!

Answers

92,000 * 100 = 9,200,000

in word form:
nine million, two hundred thousand

Final answer:

To rename the number 9,200 in hundreds, we understand that '1' in thousands is equivalent to ten hundred. Hence, 9,200 divided by 100 equals 92 but 9,200 in hundreds is represented as 9200 hundreds.

Explanation:

Renaming the number 9,200 in hundreds means we are converting the value into groups of hundreds. Since each '1' in thousands is equal to ten hundred, we multiply the value of the thousands by ten. Therefore, 9,200 divided by one hundred is 92 and if you want to represent this number in hundreds, it would be equal to 9200 hundred.
