Yes, you are correct to use proportions because they are similar triangles.
Answer:
$23.95x + $32 ≤ $440
Step-by-step explanation:
x ≤ ($440 - 400($0.08)) / $23.95
Which can be reduced to
x ≤ ($440 - 32) / $23.95
and rearranged
$23.95x ≤ ($440 - $32)
$23.95x + $32 ≤ $440
where x is an integer.
(ab + 174)/3 <115
multiply by 3 on each side
ab + 174 < 345
subtract 174 from each side
ab < 171
248+ ab >366
subtract 248 from each side
ab> 118
Answer 118< ab < 171
