4 years ago, Adrian was (x-4) + 28 = x+24 Right now, Adrian is 3x.
Knowing those two pieces of information, we can say that x+24 is equal to 3x-4. (This is because Adrian is 3x right now, and for 4 years ago, you subtract 4.)
x+24=3x-4 24=2x-4 28=2x x=14
Right now Anisah is 14, and in 4 years he will be 14+4 = 18.
1. The first step is to realize you need to find a number that will be bigger than 74. 2. All you have to do for this problem is to divide 74 by 90%. You can put this in the calculator by typing in (74 / .9). 3. The answer you get should be 82.22 4. You can check this by multiplying 82.22 by 90%, and it should bring you back to 74.
