Today only, a table is being sold for $156.60. this is 29% of its regular price. what was the price yesterday?

$ 540

Step-by-step explanation:

so 156.60 IS 29% OF its regular price..

let x represent the regular price

turn ur percent to a decimal

" is " means equals and " of " means multiply

156.60 = 0.29x

156.60 / 0.29 = x

540 = x <=== regular price

< 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)
