Answer: 43.6 (Rounded to the tenth)
Explanation: Use the method of: SOH CAH TOA.
Using TOA, T = Tangent.
tan(71) = x/15. Using the butterfly method you can just do the following equation:
15 tan(71) = 43.56 (Rounded to tenth) —> 43.6

$5.75 x 2 = 11.50
561.60 / 11.50 = 48.83 (round)

<span>−8x+5−2x−4+5x
= -5x + 1
so when x = 2 then
</span>-5x + 1
= -5(2) + 1
= -9
hope it helps
Y=25x is cheaper
Because: when x is for example 1 is 25 for acme solutions while it is almost 40 for clean sweep
