Answer:

1 % decrease

Step-by-step explanation:

The percent of decrease time can be written as the expression \frac{200}{200}-\frac{198}{200} = \frac{2}{200}. Now, we convert the fraction into a decimal: \frac{2}{200} = \frac{1}{100} = 0.01. We can convert this decimal into a percentage: 0.01*100 = 1%.

a circus sold a total of 98 adult and senior tickets to a special lion traning show adult tickets are sold for $12 each and seno
DochEvi [55]

Answer:

Correct answer: adult tickets  x = 72

Step-by-step explanation:

Given:

x = ? number of the adult tickets

y = ? number of the senior tickets

12$  adult ticket price

8$ senior ticket price

We will solve this problem using a system of two equations with two variables

x + y = 98 we will multiply whole equation with number - 2 and get:

- 2 x - 2 y = - 196

12 x + 8 y = 1072 we will divide the whole equation by the number 4 and get:

3 x + 2 y = 268

- 2 x - 2 y = - 196

we will now add the first equation to the second and get:

3 x - 2 x = 268 - 196

x = 72

x + y = 98 ⇒ 72 + y = 98 ⇒ y = 98 - 72 = 26

y = 26

God is with you!!!
