Step-by-step explanation:
On a certain hot summer's day, 691 people used the public swimming pool. The daily prices are $1.50 for children and $2.25 for adults. The receipts for admission totaled $1260.75. How many children and how many adults swam at the public pool that day?
Yes! 3x3= 9. Therefore, 3 goes into nine 3 times. So the whole number would be 3.
Answer:
A. When Katina has $280 in her bank account, 4 months have passed. Plug 4 months into Malorie's bank account equation:
a = 50(4) + 100
a = 200 + 100
a = $300
B. Malorie's bank account changes at a greater rate. Katina's bank account amount increases by $20 each month, whereas Malorie's bank account increases by $50.
Ex: month 5
Katina has 300, 20 more than the previous month.
Malorie has 350, 50 more than the previous month
The formula that explain the arithmetic sequence is 
Step-by-step explanation:
The formula of the nth term in an arithmetic sequence is
, where
- a is the first term
- d is the common difference between the consecutive terms
∵ 
, 
, 0 , 
are some terms of an arithmetic sequence
∵ The difference between two consecutive terms = -
∴ The difference between two consecutive terms = + 
=
∴ The common difference =
∴ d =
∵ The first term is
∴ a =
- Substitute a and d in the formula above
∴ 
- Simplify the right hand side
∴ 
- Add like terms
∴
