A three-bedroom house in North Augusta sold for $190,000. If housing prices are expected to increase 1.8% annually in that town,

Ivahew [28]

Answer:

we know that the initial price of the house is $190,000.

We also know that the expected increase is 1.8%, this means that the year zero we have no increase; the price is $190,000.

one year after we have an increase of the 1.8% (or 0.018 in decimal form), this means that the new price is:

$190,000 + $190,000*0.018 = $190,000*(1.018)

another year after, we have:

$190,000*(1.018)*(1.018) = $190,000*(1.018)^2

and etc

The function that models the price as a function of the years, represented as y, is:

P(y) = $190,000*(1.018)^y

If we want to know the price in 5 years, we need to replace y = 5 in the equation:

p(5) = $190,000*(1.018)^5 = $207,726.80

Evaluate: if x = 3 and y = 6 x(2x + x2 – 8y + 16)

kumpel [21]

Answer:

-60

Step-by-step explanation:

Og problem: x(2x + 2x - 8y + 16)

Substitution: 3(6 + 6 - 48 + 16)

Solve: 3(12 - 48 + 16)

3(-36 + 16)

3(-20) = -60

James invested $300 in a bank account that earns simple interest. He earns $24 at the end of 12 months. James invests $500 at th

NARA [144]

Answer: $40

Step-by-step explanation:

The key formula to use for this problem is the simple interest formula, which is $I=prt$ ; where I is the interest earned, p is the principal (initial) amount, r is the interest rate, and t is the amount of time that passes.

Since we know that both investments have the same interest rate, we can use the information from the first part of the problem to solve for the interest rate. Using algebra, we can rearrange the simple interest formula to solve for the interest rate: $r=I/pt$ . We know that our interest earned is $24 and our principal amount is $300. To make things easier, we'll also convert months to years, which is easy to do since we know that 12 months = 1 year. This gives us our value for the amount of time that passes. Now, all we have to do is plug in our values into the rearranged equation above.

We should now have: $r=\frac{24}{300*1}=0.08$

Now, to find the interest earned from the $500 investment, we just need to plug in our values from the second part of the problem, along with our calculated interest rate of 0.08, into the original formula of $I=prt$

This should result in $I=500*0.08*1=40$

Therefore, James will receive $40 on his $500 investment after 12 months.
