The local senior center is planning to take a group to see a musical production. The performance tickets are regularly priced at $40 for adults, but anyone over 65 receives a discounted ticket price of $32. The senior center has raised a total of $800 in donations to afford the trip. Which linear equation formula would you use to write the equation that represents this situation?

Calculate the surface area of the four vertical faces.
a₁ = 4*(3)(18) = 216 cm²

calculate the base area.
a₂ = (18)(18) = 324 cm²

calculate the area of the four triangular faces.
a₃ = 4*(1/2)*(18)*(41) = 1476 cm²

calculate the total surface area.
a₁+a₂+a₃ = 216 + 324 + 1476 = 2016 cm²

answer: 2016 cm²
