Answer:

amount of net income during 2006 is $65000

Step-by-step explanation:

Given data

assets in 2005 = $925,000

liabilities in 2005 = $285,000

invested an additional $50,000

withdrew $30,000

assets in 2006= $980,000

and liabilities in 2006 = $225,000?

to find out

amount of net income during 2006

solution

in 2005

assets = $925,000

liabilities = $285,000

so stock holder equity = $640000

and in 2006

assets = $980,000

and liabilities = $225,000

so stock holder equity = $725000

so retaining earning for both year is $725000 - $640000 i.e $85000

so net income = retaining earning + withdrew - investment

net income = $85000 + $30,000 - $50,000

net income = $65000

amount of net income during 2006 is $65000

You find 72 coins consisting only of nickels, dimes, and quarters, with a face value of $10.20. However, the coins all date from

Oliga [24]

Answer:

You have found 24 nickels.

Step-by-step explanation:

Let N be the number of nickles, D be the number of dimes and Q be the number of quarters. The number of coins and their face values are given by the following expressions, respectively:

$N+D+Q=72\\0.05N+0.10D+0.25Q=10.20$

As of now we have three variables and two expressions, the final expression needed to solve the linear system is given by the amount offered by the coin dealer:

$10N+20D+15Q=1,060$

Solving the linear system:

$N+D+Q=72\\5N+10D+25Q=1,020\\10N+20D+15Q=1,060\\\\10N-10N+20D-20D+15Q-50Q=1,060-(2*1,020)\\-35Q=-980\\Q=28\\\\5N-10N+10D-10D+25Q-10Q=1,020-720\\-5N+15Q=300\\-5N=300-(15*28)\\N=24$
