A Field Trip Challenge Twelve students have a challenge to sell two thousand dollars worth of pizzas to earn money for an end-of-the-year field trip. The first day each student sells twelve dollars worth of pizza. The second day each student sells twenty-four dollars worth of pizza. The third day each student sells thirty-six dollars worth of pizza. This pattern continues for one week. Do the students meet the challenge? For every twelve dollars of pizza sold, the students earn a three-dollar prot. How much money do the students earn for the field trip? Show all your mathematical thinking.

< 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)

combine all like terms then its just a 2 step equation
