Jamal has saved $2,000 for his vacation. He spends $642 on his plane ticket. How much does Jamal have to spend on the rest of his vacation?

If he has 2000 dollars to spend in total, that will go on one side of the inequality.  Everything he spends goes on the other.  2000 is the maximum he can spend.  He is going to sped 637 on an airline ticket plus x on other expenses.

2000>= 637+ x

Subtract 637 from each side

2000-637 >= 637-637 +x

1363>= x

There is a issue here...

is the spotted blue section considered "a blue sector"?

Assuming that "blue" or "red" is only a solid blue or red, this is the answer...

1)  (1/10)* (3/10) = .03

2) (3/10) * (3/10) = 9/100 = .09

3) (3/10) * (1/10) = 3/100 = .03

4) (4/10) * (3/10) = 12/100 = .12

if the spotted blue and the solid blue are considered blue then this would be the result ...

1)  (1/10)* (3/10) = .03

2) (4/10) * (3/10) = 12/100 = .12

3) (3/10) * (1/10) = 3/100 = .03

4) (8/10) * (3/10) = 24/100 = .24
