What is the sum of all integers that are multiples of 4 from 1 to 150? *Show your solution*

There's a pretty simple formula to follow: count of multiples average of the multiple.

To find the average, we take the smallest multiple of 4 which is in the range of 1 and 150 which is 4 of course. And the largest would be 148 since that's the only number in the range. So now average them:

Now we find the count of the multiples which is in the range of 1 to 150. To do that, we use this formula:

Here, is 4 so this would be:

This would give you the exclusive count of all the numbers, but we want the inclusive count so, we simple add 1 so the count would be

Now following the 1st formula we get:

So the answer would be 2812! :D

And here's the check too:

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
