Answer:
$34,000
Step-by-step explanation:
Jerry will get $1,750 for every year that his money stays in the account thus for 8 years he will get:
8*1,750 = $14,000

By the end of year 8 there will be $34,000 of Jerry's account.
Answer:
Step-by-step explanation:
Notice that the series: 1 - 3 + 9 - 27 +... clearly has powers of the factor 3 in its terms and it is also an alternate series (the terms alternate from positive to negative). The terms are positive for 
(even terms) , while the odd terms 
are negative. (so most likely there should be a factor (-1) in the common ratio.
We can then represent it with the following summation expression:
given that each of its first four terms are:

Answer:
6 over 1/24
Step-by-step explanation:
You can find the quotient of 9 2/3 divided by 1 3/5 by first making the two terms into improper fractions.
To make the improper fractions, you can turn 9 2/3 into 29/3 by multiiplying 9 by the denominator (bottom number in fractions) and adding that to the numerator of 2 which gives 29.
1 3/5 can turn into 8/5.
Then you can divide using a simple trick of first organizing the data.
Currentlly it should be
29/3 divided by 8/5
Then you can flip the second fraction over.
29/3 divided by 5/8
Then you change the sign into multiplication.
29/3 times 5/8
Then you multiply like normal.
29 times 5 over 3 times 8
145 over 24
You can simplify now
6 over 1/24
Hope this helps!
