Convert the dollar amounts to cents to make the math easier.

$2.20 = 220¢
$2.35 = 235¢

The original price is 100%
The new price is x%

220/235 ≈ <span>0.93
</span>
Convert decimal into a percent by moving the decimal two places to the right and adding the % sign.

0.93 = 93%

100% - 93% = 7%

So, there was a 7% decrease in price.

B = 8*9/2

B = 72/2

B = 36 square feet

C = total area

C = A+B

Express in exponential form 200×75​
GREYUIT [131]

Do you mean exponential form as in scientific notation or as in prime factorization.

Now matter I will do both.

As in scientific notation.

200*75

=150*100

=1.5*10000

=1.5*10^4

As in prime factorization.

200*75

=2^3*5^2*3*5^2

=2^3 * 3 * 5^4

Do the one your teacher ask for :) Hope it helps!

Answer:

Option (2)

Step-by-step explanation:

x = 1 is represented by a solid point on a number line.

From the options given,

Arrow mentioned in Option (2) will be the correct representation of the inequality.
