The salespeople at a local car dealership are paid a commission based on the profit earned from each car they sell. if the profit is less than $900, the salesperson gets 15% of the profit as commission. if the profit on the car is equal to or between $900 and $1,500, the salesperson gets 17% of the profit. even better, if the profit on the car sold is more than $1,500, the salesperson gets 21% of the profit as commission. write a function that relates the commission earned by a salesperson, c(p), to the profit earned on the car, p.

< 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)
