Answer:

A

Step-by-step explanation:

Equation

300 ( 1 + x) = 420

Explanation

You start with 300. What fractional amount do you need to increase the original amount up to 420

Solution

Divide both sides by 300

300(1 + x)/300 = 420/300

1 + x = 1.4    

Subtract 1 from both sides.

1 - 1 + x = 1.4 - 1

x = 0.4

But as a percent this number is 0.4 * 100 = 40%

Answer

40% which is A

A hair cut cost $25 and you want to leave a 15% tip what is the total bill?
Olin [163]
You need to change 15% to a decimal and multiply it by 25

25 x 0.15 = 3.75

Then add 3.75 to 25 to get the total

25 + 3.75 = 28.75

So, the answer is 28.75$

Hope it helps :)
