Mathematical information of other scenic spots
This is the topic in the final examination paper of the fourth grade in Zhonghe Town, Tengchong on 20 17-20 18.

The complete topic is: Autumn is coming, and Ginkgo Garden Scenic Area is open to tourists. There are two ways to charge tickets for scenic spots: way 1: adults 15 yuan and children's 7 yuan. Option 2: Group tickets can be purchased for more than 10 people, and each group ticket is 10 yuan. If there are three adults and seven children, which way is cost-effective?

Answer analysis: Method 1: 15*3+7*7=45+49=94 yuan; Method 2:10 * (3+7) =10 *10 =100 yuan, 100 > 94. The method 1 is economical.
