Question

Help please?

Answer 1

there are two types of floats

large and small

let

x = # of large floats
y = # of small floats

Answer 2

the big floats need 30+10 = 40 ft

so if you have x of them, then you use up 40x ft so far

----------

one small float takes up 15+10 = 25 ft

so you need 25y feet for y small floats

Answer 3

in total, you take up 40x + 25y feet

this total must be between 150 ft and 200 ft, so

\[\large 40x+25y \ge 150\]

and

\[\large 40x+25y \le 200\]

Answer 4

If you graph those two inequalities, then you'll get the solution set, which will lead you to the possible combinations of large and small floats
