Answer:
<u>There were 6, 9, 12 and 15 children if the number of adults at the beach were 8, 12, 16 and 20.</u>
Step-by-step explanation:
After reviewing the information given for solving the question, we notice that the number of adults and the number of children are two constants, where the number of children is the 75% of the number of adults (3/4 = 75%). In that case, for finding the number of children for every specific number of adults, we do the following calculations:
1. For 8 adults: Using the 75%, we multiply by it (8 * 75%) and we get that the number of children is 6.
2. For 12 adults: Using the 75%, we multiply by it (12 * 75%) and we get that the number of children is 9.
3. For 16 adults: Using the 75%, we multiply by it (16 * 75%) and we get that the number of children is 12.
4. For 20 adults: Using the 75%, we multiply by it (20 * 75%) and we get that the number of children is 15.
<u>There were 6, 9, 12 and 15 children if the number of adults at the beach were 8, 12, 16 and 20.</u>
Answer:
The situation represents the arithmetic sequence
Step-by-step explanation:
∵ The cost of the first night is $240
∵ The cost of each night after the first is $210
∵ The number of nights is x
∵ The total cost of staying at the hotel x nights is y
∴ y = 240 + 210(x - 1)
Put x = 1 , 2 , 3, 4 and then check the type of the sequence
∴ y = 240 + 210(1 - 1) = 240
∴ y = 240 + 210(2 - 1) = 450
∴ y = 240 + 210(3 - 1) = 660
∴ y = 240 + 210(4 - 1) = 870
∵ The difference between each two consecutive terms are constant
(450 - 240 = 210 , 660 - 450 = 210 , 870 - 660 = 210)
∴ The sequence is arithmetic sequence
