Answer:

30% discount

Step-by-step explanation:

To find the percent discount write a proportion.

$\frac{1344}{1920}=\frac{x}{100}$

Cross multiply numerator with denominator of each fraction to solve for x.

1344(100) = 1920(x)

134400 = 1920x

70 = x

This means you pay 70% of the price. The discount was 30%.

suppose that during one period of extreme cold the average daily temp decreased 1 1/2 Fahrenheit each day how many days did it t

Nina [5.8K]

Answer:

The temperature decreased by 9 °F in <u>6 days.</u>

Step-by-step explanation:

Let the number of days it takes for the temperature to decrease by 9 °F be $x$ .

Given:

Average daily temperature decreases by $1\frac{1}{2}$ °F.

Decrease of temperature in 1 day = $1\frac{1}{2}$ = 1.5 °F.

∴ Decrease in temperature in x days is $1.5x$ .

Now, as per question, decrease in temperature in 'x' days is 9 °F.

Therefore, $1.5x=9$

$x=\frac{9}{1.5}$

$x=6$

Therefore, the temperature decreased by 9 °F in 6 days.
