Someone
8. the art department at a school sold 323 tickets
to an art show, for a total of $790. students paid
$2 for tickets, and non-students paid $3.50. the
principal asked how many non-students
attended the art show.
a) write a system of two linear equations
for this situation.
b) solve the problem by graphing the system.

Step-by-step explanation:

students = x

non-students=y

x+y=410

y=410-x

3x+7y=1650

3x+7(410-x)=1650

3x+2870-7x=1650

-4x=-1220 (divide both sides by -4)

x=305 y=410-305=105

Hence, 305 students attended and 105 non-students attended

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
