Answer:
first he had M some unknown amount
then he had 2/3 M since he spent 1/3 M
then he spent 3/4 of the (2/3 M) so he had 1/4 of the ( 2/3M)
then he spent what was left $20 so $20 = 1/4 ( 2/3 M) now solve for M
and check by doing each step and figuring how much was spent and how much left.
<u>another</u><u> </u><u>method</u><u> </u>
let us consider the left amount be Y and total now of M dollar be X
then
Y = amount of money Nartin has left
Y = X - ( 1/3 ) ( X ) - ( 3/4 ) ( X - 1/3 X ) - 20
Y = X - 1/3 X - 3/4 X + 3/12 X - 20
Y = X - 4/12 X - 9/12 X + 3/12 X - 20
Y = X - 10/12 X - 20
Y = X - 5/6 X - 20
Y = ( 1 / 6 ) ( X ) - 20

The expression:
3 (x - 2)
indicates that the number 3 before the parenthesis is multiplying the expression inside the parenthesis.
Then in order to do such we use what is called the distributive property which tells us to "distrubute" suche multiplication among the two term that are in the parenthesis:
3 x - 3 * 2
3 x - 6
Which is the first option in your answer list.
