Question

Can someone help me on a linear inequalities problem?

Answer 1

First, step.... what type of tickets are being sold ?

Answer 2

adult and children

Answer 3

yes. The question asks "how many tickets have to be sold"

So we are interested in the *number of adult* and *number of children* tickets.

2nd step: give "number of adult tickets" a "name" : call it A
same for # of children tickets: call the number C

Answer 4

if you sold A tickets and C tickets, the total is A+C

what is the most A+C can be ?

Answer 5

You do know it is a bad idea to sell more tickets than you have seats for, right ?

Answer 6

Yes and we only have 240 seats

Answer 7

so A + C < = 240

Answer 8

and 8a + 4c <= $1000

Answer 9

This one?

Answer 10

yes this one

Answer 11

What is the matter with the answers you have already been given?

Answer 12

I got 2 equations
a + c < = 240
8a + 4c <= 1000

Answer 13

I wanted to know if I was right

Answer 14

yes. They are right except the second one should be greater than or equal because they need at least $1000 and I'm pretty sure they won't care if they make more than that.

Answer 15

okay so 8a + 4c >= 1000

Answer 16

then I solve it?

Answer 17

yes

Answer 18

would you mind helping me on that part

Answer 19

I would solve that second one by 4 to make the numbers smaller.

Answer 20

Solve them both for y

Answer 21

okay let me try one sec
