Answer:
1/11
Step-by-step explanation
There are 12 marbles in the bag. When we first pick we have 4 blue marbles. So 4 blue marbles/12 random marbles. When we pick blue and noted, there are 3 marbles in the bag because of we didn't put it back. So when we choose again there are 11 marbles and 3 blue marbles in the bag. Choosing a blue one case is 3/11.
The last part of this case is happening as a chain. So we need to multiply our two answers.
=4/12*3/11
=1/3*3/11
=1/11
9 and 12 are slope-intercept form and 10 and 11 are point-slope form
Marks UP the price by 30%.
There's two ways:
30% of $22, plus $22.
OR
130% of $22.
To save time, 130% of 22.
130/100 x 22
= 13/10 x 22
=13/5 x 11
=143/5
= 28.6
$28.6
Hope this helps!
