1. 800 tickets were sold for a Rock Music Concert with a total revenue of $7500. If
adult tickets were sold for $12 and students
tickets were sold for $8. How many of each
type of ticket were sold?

I will set it up for you only.

Let a = adult tickets

Let s = student tickets

Here is your system of equations:

a + s = 800

12a + 8s = 7500

Take it from here.

i would say the third one.

step-by-step explanation: liner would mean in a line and the only one that doesn't look like it's even thinking about forming a line would be the third one

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
