A warehouse store sells 6.5-ounce cans of tuna in packages of 6. A package of 6 cans costs $14.82. The store also sells 3.5-ounce cans of the same tuna in packages of 3. A package of 3 cans costs $3.57. The store sells 4.5-ounce cans in packages of 5 cans for $8.10. Which package is the best buy? I need the answers asap

< 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)
