The formula you need is: S = (n/2) (2a1 + (n - 1) x d)
so then you plug in the numbers:
S = (365/2) (2 x 1 + (365 - 1) x 1)
then combine like terms:
S = 66795 pennies
A dollar is 100 pennies. Therefore, at the end of the year, the total savings is $667.95.
She had 1 bear left over.
That means she was able to divide 51 bears evenly.
51 can be divided by only 2 numbers (other than 1 and 51), NAMELY, 3 and 17, both of which are prime.
She either made 17 groups of 3 or 3 groups of 17.
Either way, she'd use 51 bears and have 1 left over.
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>
