Answer:
24 years old
Step-by-step explanation:
Let Malvin's age be x.
- x / 2
- x / 2 + 5 = 5x / 10 [ By taking the L.C.M.]
- ( 5x / 10 ) * ( 1 / 3 ) = 5x / 30 [ Multiply with the reciprocal of 3 ]
- ( 5x / 30 ) * 2 = 5x / 15
Now let's solve the equation,
5x / 15 = 8
5x = 8 * 15
5x = 120
x = 120 / 5
x = 24
Therefore, Malvin is 24 years old.

<u>Answer:</u>
$180
<u>Explanation:</u>
Alright, this took me a second of thinking.
So let's say our original price is x. Now to get to the discounted price of 135, we had to take off 25%. Because we know 25% of x is now gone, 135 must be 75% of x. So in this case we would divide 135 by .75 and that would give us 180.
Now to check this out, we just have to remove that 25% and see if we still get 135. So when we multiply 180 x .25 we get 45. Then subtracting our 45 from 180 we get 135, proving that the original price is indeed $180.
