Which of the following options have the same value as 30\%30%30, percent of 818181?
Nataly_w [17]

Answer:

Option B is correct = 0.3 \times 81

Step-by-step explanation:

<u>The complete question is:</u> Which of the following options have the same value as 30% of 81?

Group of choices is:

(A) \frac{30}{100}\times 81 \times 100

(B) 0.3 \times 81

(C) 0.03 \times 81

(D) \frac{3}{10}\times 81 \times 10

(E) 30 \times 81

Now, the expression given to us is 30% of 81.

Simplifying the above expression we get;

   30% of 81  =  \frac{30}{100} \times 81

                     =  \frac{3}{10} \times 81  =  0.3 \times 81

Now, we will solve each of the given options and then see which option matches with our calculation.

Option (A) is given;

\frac{30}{100}\times 81 \times 100  =  30 \times 81

This doesn't match with our answer, so this option is not correct.

Option (B) is given;

0.3 \times 81  

<u><em>This matches with our answer, so this option is correct.</em></u>

Option (C) is given;

0.03 \times 81  

This doesn't match with our answer, so this option is not correct.

Option (D) is given;

\frac{3}{10}\times 81 \times 10  =  3 \times 81

This doesn't match with our answer, so this option is not correct.

Option (E) is given;

30 \times 81  

This doesn't match with our answer, so this option is not correct.

At a local gym you go to, you either pay $90 fee for a monthly pass, and an additional $4 for each time you decide to go to the
Vikentia [17]

Answer: C. 10.

Step-by-step explanation:

Let x = Number of times you have to go to the gym in order for it to cost the same amount.

Given: Monthly pass fee = $90

Additional charge = $4

Total amount = (Monthly fee)  + (Number of times) (Additional charge)

Total amount = 90+4x                (i)

Payment for each time you go to the gym = $13

Total amount = 13x                    (ii)

From (i) and (ii) , we get

13x=90+4x\\\\\Rightarrow\ 13x-4x=90\\\\\Rightarrow\ 9x=90\\\\\Rightarrow\ x=\dfrac{90}{9}\\\\ \Rightarrow\ x= 10

Hence, the number of times you have to go to the gym in order for it to cost the same amount= 10

Hence, the correct option is C. 10.
