The equation 10.50 a plus 3.75 b equals 2071.50, where a is the number of adult tickets sold and b is the number of student tickets sold, can be used to find the number of adult and student tickets.

Answer 2

Answer:

168

Step-by-step explanation:

The first equation given is $0.50 a +3.75 b= 2071.50$

Where a is number of adult tickets and b is number of student tickets

It is also given that 82 students attended, so we can put "82" in place of "b" and then solve the equation for a:

$10.50a+3.75b=2071.50\\10.50a+3.75(82)=2071.50\\10.50a+307.5=2071.50\\10.50a=2071.50-307.5\\10.50a=1764\\a=\frac{1764}{10.50}\\a=168$

Hence, 168 adults attended
