The given percent above is 215%. To convert this into decimal, let us divide this by 100. 215 / 100 and we get 2.15. So the decimal form of 215% is 2.15. Next, convert it into a fraction. Given the decimal form of 2.15, this is already equivalent to 2 15/100. To simplify this, since both 15 and 100 are divisible by 5, we get 3/20. Therefore, the fraction is 2 3/20. So the correct answer is option B. 2.15; 2 3/20.

Regal theater in Tikahtnu sold 548 tickets to Moana on Sunday. A adult’s ticket was $6.50 while a child’s ticket was $3.50. In t

Regal theater sold 321 adult tickets and 227 children tickets.

Step-by-step explanation:

Given,

Cost of each adult ticket = $6.50

Cost of each child's ticket = $3.50

Total tickets sold = 548

Total worth of sold tickets = $2881

Let,

x represent the number of adult tickets sold

y represent the number of child tickets sold

According to given statement;

x+y=548             Eqn 1

6.50x+3.50y=2881    Eqn 2

Multiplying Eqn 1 by 6.50

6.50(x+y=548)\\6.50x+6.50y=3562\ \ \ Eqn\ 3

Subtracting Eqn 2 from Eqn 3

(6.50x+6.50y)-(6.50x-3.50y)=3562-2881\\6.50x+6.50y-6.50x-3.50y=681\\3y=681

Dividing both sides by 3

\frac{3y}{3}=\frac{681}{3}\\y=227

Putting y=227 in Eqn 1

x+227=548\\x=548-227\\x=321

Regal theater sold 321 adult tickets and 227 children tickets.

I know the answer is .78, but don’t understand why? .9-.6X.2
ladessa [460]
0.6 x 0.2 = 12 and .9 - .12 = .78

It may be confusing because the decimals aren’t like whole numbers.

Blizzard [7]
For this case, the first thing to do is find the equation of the line in order to model the problem mathematically.
 Using Excel (see attached image) we find that the equation of the line is:
 y = 0.0035x - 3

 We evaluate for:

 For x = 7000:
 y = 0.0035 * (7000) - 3
 y = 21.5 $

 For x = 10000
 y = 0.0035 * (10000) - 3
 y = 32 $

 For x = 13000
 y = 0.0035 * (13000) - 3
 y = 42.5 $

 Answer:
 The total water cost when the barber shop uses 7,000 gallons, 10,000 gallons, and 13,000 gallons is:
 21.5 $, 32 $, 42.5 $, respectively.
