James has $5.00 more than three times what Catherine has. Together they have $41.00. How much does each student have?
Tpy6a [65]
Hey.

acc'g to the conditions :

Let Catherine has x
and James has 5 + 3x

Then,

5 + 4x = 41 \\ \\ \implies 4x +5 -5 = 41-5 \\ \\ \implies 4x = 36 \\ \\ \implies x= \dfrac{36}{4} \\ \\ \implies x = 9

Hence

• Catherine has = x = $9,
• and James has = 5 +3x = 5 + 3(9) = $32

Thanks.

The starting salary at a company is $42,000 per year. The company automatically gives a raise of 3% per year. Write a recursive
cricket20 [7]
To solve this, we are going to use the recursive formula for a geometric sequence: a_{n}=a_{1}r^{n-1}
where
a_{n} is the nth term of the geometric sequence.
a_{1} is the first term of the geometric sequence.
r is the common ratio 
n is the position of the term in the sequence. 

We know that the starting salary is $42,000, so a_{1}=42000. Now, to find the common ratio r, we need to find the next term in the sequence first:
We know from our problem that t<span>he company automatically gives a raise of 3% per year, so the next term in the sequence will be 42000 + 3%(42000) = 42000 + 1260 = 43260. Remember that the common ratio is the current term of the geometric sequence divided by the previous term of the sequence; we know that our current term is 43260 and the previous term is 42000, so:
</span>r= \frac{43260}{42000}
r=1.03
<span>Now we can plug the values in our recursive formula:
</span>a_{n}=a_{1}r^{n-1}
a_{n}=42000(1.03)^{n-1}

We can conclude that the recursive definition for the geometric sequence formed by the salary increase is: a_{n}=42000(1.03)^{n-1}
