13. The cost of admission to the Baytown Zoo is $10.50 for each senior citizen, $15.75 for each adult, and 58 25 for each child.

Part A

A family of 2 adults and 1 child plan to spend the day at the Baytown

Zoo. How much does admission for the family cost? Explain how you

found your answer.

Part B

Describe another way you could solve the problem.

Part

What if 2 more tickets for admission are purchased? If the two additional

tickets cost $16.50, determine what type of tickets the family purchases.

Explain how you can determine the answer without calculating.

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality

step-by-step explanation:

m

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)
