Answer:

We have this equation:

0.4y - 0.2y + 10 = 11.8

You can simplify

0.2y + 10 = 11.8

Then, you can substract 10 in both sides:

0.2y = 11.8 - 10

0.2y = 1.8

You can now divide right and left side by 0.2 and get y:

0.2y/0.2 = 1.8/0.2

y = 14

Where

P represents principal or amount invested.

T represents the time

R represents the interest rate

I represents the interest

From the information given,

You want to put $580 into a saving account for 1 year. This means that

P = $580 and

R = 6 1/2 = 6.5%

I = (580× 6.5×1)/100 = $37.7

ivann1987 [24]

Answer:

The final answer is "$2387.85 and $2594.85".

Step-by-step explanation:

Given values:

The bank statement balance= $2,253.18

The checkbook balance = $2,324.34

outstanding check amounts= $105.50 and $158.10

transit amount= $605.27

account earnin(credits)= $68.51

service charge= $5.00

Adjusted Checkbook Balance =?

Adjusted Statement Balance=?

Adjusted the Checkbook Balance:

checkbook balance = $2,324.34

$\text{total checkbook balance = checkbook balance+ credits}\\$

$= \$ 2,324.34+ \$ 68.51\\\\= \$ 2392.85$

$\text{ Adjust check book balance= total checkbook balance - servicec charge}$

$= \$2392.85 - \$5.00\\\\= \$ 2387.85$

Adjusted the Statement Balance:

bank statement balance= $2,253.18

$\text{total Statement balance = bank Statement balance+ transit amount}\\$

$= \$ 2,253.18+ \$ 605.27\\\\= $ 2,858.45$

$\text{outstanding check amounts = $105.50+ $158.10}$

$= \$263.60$

$\text{ Adjust statement balance= total statement balance - outstanding check amount }$ $= \$ 2,858.45 - \$263.60\\\\= $ 2,594.85$
