Sabor inc. is a medical testing laboratory that performs several tests and analyses for hospitals in the area. four of the tests that they perform require the use of a specialized machine that can supply 14,000 hours per year. information on the four lab tests follows: test a test b test c test d charging rate $65 $51 $48 $32 variable cost $25 $18 $13 $8 machine hours 3 2 1 0.5 what is the contribution margin per hour of machine time for test a? a.$25.50 b.$40 c.$65 d.$15.67 e.$13.33

hi there! my name is zalgo and i am here to you out today. the answer is pretty simple (in a way). this equation equals to 25.2!

i hope this answer !

step-by-step explanation:

< xcy ≅ < xby

step-by-step explanation:

in δcax and δbax,

so, δcax ≅ δbax (side-angle-side or sas)

since δcax ≅ δbax, we can conclude < acx ≅ < abx

in δacy and δaby,

so, δacy ≅ δaby (side-angle-side or sas)

since δacy ≅ δaby, we can conclude < acy ≅ < aby

now,

< acy ≅ < aby

=> < acx + < xcy ≅ < abx + < xby

=> < acx + < xcy ≅ < acx + < xby   (since < acx ≅ < abx already proved above)

subtracting < acx from both sides, we get

< acx + < xcy -< acx ≅ < acx + < xby -< acx

cancelling out < acx and -< acx from both sides, we get

< xcy ≅ < xby (proved)

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct
