MaRussiya [10]

Answer:

In the year 2010, the population of the city was 175,000

Step-by-step explanation:

If we rewrote this as a linear expression in standard form (it is linear, btw), it would look like this:

$P(t)=\frac{11}{2}t+175$

The rate of change, the slope of this line, is 11/2. If the year 2010 is our time zero (in other words, we start the clock at that year), then 0 time has gone by in the year 2010. In the year 2011, t = 1 (one year goes by from 2010 to 2011); in the year 2012, t = 2 (two years have gone by from 2010 to 2012), etc. If we plug in a 0 for t we get that y = 175,000. That is our y-intercept, which also serves to give us the starting amount of something time-related when NO time has gone by.

19. The marked price of an oven is 30% above its cost. In a sale, it is

yaroslaw [1]

a) Marked price: $884, Cost: $680

b) 2.5 %

Step-by-step explanation:

a)

Let's call:

P = marked price of the oven

C = cost of the oven

We know that:

- The marked price of the oven is 30% above the cost, which means

$P=(1+\frac{30}{100})C=1.30C$ (1)

- In the sale, the oven is sold at a discount of 25% on its marked price; so the price of the sale is (we call it S)

$S=(1-\frac{25}{100})P=0.75P$ (2)

- We also know that the discount, which is the difference between the makerd price (P) and the discounted price (S) is

$P-S=\$221$ (3)

Substituting (2) into (3) we find marked price

$P-0.75P=\$221\\0.25P=\$221\\P=\frac{221}{0.25}=\$884$

Therefore, the cost of the oven is (from eq(1)):

$C=\frac{P}{1.30}=\frac{884}{1.30}=\$680$

b)

The percentage loss in this situation is given by the difference between cost of the oven and the final price at which the oven is sold.

In this case, we have:

C = $680 (cost of the oven)

The discounted prices is S, and can be f ound using eq(3):

$S=P-221=884-221=\$663$

Therefore, the oven costs 680$ but it is sold at 663$.

Therefore, we can calculate the percentage loss using the equation:

$Loss=\frac{C-S}{C}\cdot 100 = \frac{680-663}{680}\cdot 100 =0.025\cdot 100 = 2.5\%$

So, a percentage loss of 2.5%.

Edward deposited $9,000 into a savings account 2 years ago. The simple interest rate is 4% How

BARSIC [14]

Answer:

$734.40

Step-by-step explanation:

y=9,000(1.04)^t is our equation for this.

The 9,000 is the starting amount.

1.04 is the 4% since 4% is 4/100 which equals 0.04, then we add 1 to that since it's increasing in value.

y represents our output.

t represents time (in years for this equation)

Since they give us the amount of years since he deposited the $9,000, we put the number they gave us (2 years) into the equation, replacing t.

y=9,000(1.04)^2

Put the right side into a calculator and it gives you 9734.4.

That's the total amount he has now, so to find how much he earned we subtract the starting amount (9000).

734.4.

Edward earned $734.40.
