Suppose that work hours in new zombie are 200 in year 1 and productivity is $8 per hour worked. what is new zombie's real gdp? i
olasank [31]
Given that <span>work hours in new zombie are 200 in year 1 and productivity is $8 per hour worked.

The new zombie's real gdp in year 1 is given by 200 x $8 = $1,600

If work hours increase to 210 in year 2 and productivity rises to $10 per hour.

The new zombie's real gdp in year 2 is given by 210 x $10 = $2,100

The new zombie's rate of economic growth is given by

\frac{\$2,100-\$1,600}{\$1,600} \times 100\%= \frac{\$500}{\$1,600} \times100\%=31.25\%</span>

jessica weighs x+34 pounds and Ronda weighs 12 pounds less. If Jessica gains 5 pounds and Ronda loses 2 pounds, what is the sum
Vladimir [108]

Answer:

2x+59.

Step-by-step explanation:

Let <em>J </em>represent Jessica's weight and <em>R</em> represent Ronda's weight.

Jessica weighs <em>x+34</em> pounds. Thus:

J=x+34

Ronda weighs 12 pounds less than Jessica. In other words:

R=J-12=(x+34)-12\\R=x+22

The sum of their weights, therefore, is:

J+R\\=(x+34)+(x+22)=2x+56

Now, if Jessica gains 5 pounds and Ronda loses 2 pounds, the net gain of the total weight would be 3 pounds. Thus, we only need to add 3 to the original total to find the sum of their new weights:

2x+56+3=2x+59

The sum of the new [weights] is represented by 2x+59.
