A little help pls

Question

I forgot how to let the program Calculate the percentage of smth

Answer 1

Think of percent as "per cent". That means per 100.

The word "per" implies using a division operation. Another way to say it is "divide by 100".

So, 25 percent is (25/100).

When you see the word "of" in mathematics, it usually means multiply.

So 25 percent of 80 means:

(25/100) * 80
= (0.25) * 80
= 20

If you are working with integers then (25/100) would become 0. It is best to perform the multiplication first, and then the division without parentheses.

This will produce correct results for integers:

80 * 25 / 100

Answer 2

In the Paint Costs task, calculate the cost and tax separately. Then add them together. The final step is to round up. Don't simply round it. You should use the ceil() function to round up.

Answer 3

At this point I will need to see your code. Maybe I can spot something that you overlooked. Would you mind posting it here, or better yet, a link to the code in the playground?

Answer 4

Ah

Answer 5

I tried it and it doesn't work good

Answer 6

I'm trying to do the c# challenge named paint costs, and there is still smth wrong

Answer 7

I already did

Answer 8

But it doesn't work, 2 of the 5 objectives are still undone

Answer 9

Ok
