A bag is on sale for $30. If the sale is 25% off, what was the original price of the bag? Explain your thinking
Eva8 [605]

Answer:

30x25/100

25%=7,5$

30+7,5$=37,5$

The original price was 37,5 because you had to first find out what was 25% in $ to then do the opposite of a sale since we are finding the original price so we have to add it to 30$ since 30$ was the price after the sale.

Hope this helps, have a good day!

Pls mark brainliest :))

julsineya [31]

Answer:

11

Step-by-step explanation:

Method A

(3*\pi )*11\approx103.62

(4*\pi )*11\approx138.16

138.16-103.62=34.54

34.54\div\pi\approx11

Method B

3\pi*11=33\pi

4\pi*11=44\pi

44\pi-33\pi=11\pi

If the crane operator works 30 years and the train engineer works 33 years, who makes the most lifetime income? How much more?
antiseptic1488 [7]

Answer:

The train eingineer.

Step-by-step explanation:

So, to find the lifetime income, we must multiply the annual income by the years of work.

So for the cran operator:

54,830*30

=

1,644,900

Now lets compare this to the train eingineer:

50,610*33

=

1,670,130

So looking at the two numbers:

<u>1,670,130(train eingineer)</u>>1,644,900(crane operator)

So the trian eignineer makes more than the crane operator.

Now lets find the amount.

To do this, lets subtract the larger value by the smaller value:

1,670,130-1,644,900

=

<u>25,230</u>

So the train eingineer made 25,230 more dollars than the crane operator.

Hope this helps!
