Answer:

Option (B) 276.75

Step-by-step explanation:

Distance covered by Sara in 3.2 gallons of gas is 72 miles.

So, distance covered by Sara in 1 gallon of gas is \frac{72}{3.2} miles

Now, we need to find the total distance covered by Sara in 12.3 gallons of gas, to find we need to multiply 12.3 and the distance covered in 1 gallon.

So, distance covered in 12.3 gallons of gas

=\frac{72}{3.2}\times 12.3

=\frac{720}{32}\times \frac{123}{10}

=\frac{72\times 123}{32}

=276.75 gallons

Hence, option (B) is correct.

astra-53 [7]

Answer:

When Aria sold her house after eleven years it worth was <u>$95,300</u>.

Step-by-step explanation:

Given:

Aria paid $75,000 for her house. Its property value increased by 2.2% per year.

Now, to find the worth of Aria house when sold after eleven years.

Let the amount of house after eleven years be x.

Amount Aria paid for her house (A) = $75,000.

Rate of property increased per year (r) = 2.2%.

Time (t) = 11 years.

Now, to get the amount of house after eleven years we put formula:

x=A\times (1+\frac{r}{100})^{11}

x=75000\times (1+\frac{2.2}{100})^{11}

x=75000\times (1+0.022)^{11}

x=75000\times (1.022)^{11}

x=75000\times 1.2704

x=95280.

<em>The amount of house after eleven years to the nearest hundred dollars is $95,300.</em>

Therefore, when Aria sold her house after eleven years it worth was $95,300.
