The total number of eggs in k cartons where each carton contains n eggs. Write this as an expression.
Liula [17]

。☆✼★ ━━━━━━━━━━━━━━  ☾  

It makes more sense if you think about it in numerical terms.

Say if there were 10 eggs per carton and there were 5 cartons, what would you do to find the total?

You would multiply them

It is the same in this case

The expression would be n x k

It can be written as just nk though

A student theatre charges $9.50 per ticket. The theater has already sold 70 tickets. Write and solve an inequality that represen
Leona [35]
To make the inequality, we will use the ≥ sign to determine how many more tickets we will need. Before we write the inequality, let's see how much money was already made by the present tickets. 70 x 9.50 = $665.
We can write the inequality as $665 + $9.50t ≥ $1000 where t is the number of tickets sold. Now we can solve
$665 + $9.50t ≥ $1000, subtract 665
$9.50t ≥ $335. Now isolate the t by divide 9.50 to both sides
t ≥ 35.26 which we can round up to 36 because you cant sell 35.26 tickets. 
So you need at least 36 more tickets to earn at least $1000
