8) Tinseltown charges $9 for adult tickets and $5 for student tickets. For the 7:30 showing of Sonic the
Hedgehog they sold 200 tickets for $1528. This is reflected in the following equations:
a + s = 200
9a + 5s = 1528
How many student tickets were sold?

68 students tickets were sold.

Step-by-step explanation:

Given equations are;

a + s = 200     Eqn 1

9a + 5s = 1528   Eqn 2

The equation shows that a represent number of adults and s represent number of students, therefore, we will eliminate

Multiplying Eqn 1 by 9

Subtracting Eqn 2 from Eqn 3

Dividing both sides by 4

68 students tickets were sold.

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
