During the "June 1st" festival, my father and mother took Xiao Ming to the Science Palace to visit the reptile exhibition. The cost of buying tickets was 24.5 yuan. It is known that the price of one adult ticket is equal to the price of three children's tickets. How much is one adult ticket?
"六一"节时，爸爸、妈妈带小明去科学宫参观爬行动物展，买门票共用去24.5元，已知一张成人票价与三张儿童票价相等，一张成人票多少元呢？
