Do 2x2 first which is 4 and then 5+12 which is 17 . 17/4 is 4.25
You are correct. For each of the three possibilities for their second day, there are two possibilities for the third day.
The total number of possibilities is 3*2 = 6.
Start by distributing the - 1/3 which is the same as dividing the entire parentheses by 3 which results in (3x+10)
120 % = 160
---------------------------------------------------------------------------
Find 1 % :
---------------------------------------------------------------------------
120% = 160
1% = 160 ÷ 120
1% = 4/3
---------------------------------------------------------------------------
Find 100% :
---------------------------------------------------------------------------
1% = 4/3
100% = 4/3 x 100
100% = 133 1/3
---------------------------------------------------------------------------
Answer: 160 is 120% of 133 1/3
