Jerry earned $18,500 one year and then received a 10.5%Business and finance. Jerry earned $18,500 one year and then received a 10.5%raise. What is his new yearly salary?


Yi Chen made a $6,400 investment at the beginning of a
year. By the end of the year, the value of the investment had decreased by 8.2%.What was its value at the end of the year?

Answer 1

8,882 * .85 = 7549.7

$18,500 * .105 = $1,942.5 + $18,500 = $20,442.5

$6,400 * .082 = $524.8... $6,400 - $524.8=
$5,875.2
I hope Its not too late...................

Answer 2

QUESTION 1

Gasoline = 85% of Motor fuel
Motor fuel = 8882 bbl
Gasoline
= (85/100) x 8882
= 7549.7 bbl
= 7550 bbl (nearest whole number)


QUESTION 2

I don't really get the phrasing of this question, but if you're just asking how much Jerry will get after a 10.5% raise after one year,

New salary
= 18500 + (10.5/100)(18500)
= $20,442.50


QUESTION 3

Value of investment at beginning of year = 6400
Value of investment at end of year
= 6400 - (8.2/100)(6400)
= $5,875.20


Hope this helps! =)

Answer 3

1. 8,852 x .85= 7,524.2 or 7,524 rounded down to the nearest whole number.

2. 18,500 x .105 =1942.50 18,500+1,942.50= $20,442.50.That is his new salary,round up to the next dollar if rounding is needed.

3. 6,400 x .082 = 524.8 is the subtrahend. 6,400-524.8= $5,875.20 made in investments.Round down if needed.

Answer 4

1) use proportions- 85% is equal to 85/100.
85/100 = n/ 8882
cross multiply 100n= 85 * 8882
100n = 754970 divide by 100 n= 7549.7 nearest barrel= 7550 barrels

2) 18500 * 10.5% = 1942.5 + 18500 = 20442.5

3) . 6400 * 8.2% = 524.8 then you subtract because it's a decrease.
6400 - 524.8 = 5875.2

Answer 5

1. 85% of 8882 is 7549.7 bbl
8882 x .85 = 7549.7

2. 18500 x 10.5% = 1942.5 is the raise, his new salary is the old salary plus the raise,
18500 + 1942.5 = 20442.5

3. 6400 x 8.2% = 524.8
6400 - 524.8 = 5875.2

Answer 6

8,882 * .85 = 7549.7 rounded to 7550 bbl/day

18,500 * (1+.105) = 20,442.5

6,400 * (1-.082) = 5,875.2
