You have $60.00.
Each CD (x) is $11.00.
11x ≤ 60
The number of CDs multiplied by the cost (11) has to be less than or equal to 60.
x ≤ 5.45
You can only buy 5 CDs.
x y
------ -----
-9 -2
-5 -7
-1 -12
3 -17
ur x's all have a difference of 4, and ur y's all have a difference of -5...so yes, this is linear with a slope of (-7+2) / (-5 + 9) = -5/4
Answer:
$1382
3455 is 5/7 of salary so divide 3455/5 = 691
then multiply 691x2 because rent is 2/7 of salary
691x2 = 1382
