at a movie theater, childrens tickets cost $5 each for people aged 12 years and younger and adult tickets cost $8 each for people aged 13 years and older. The movie theater made $480 in ticket sales.

First restaurant price: 29 + 6l = x

x = final cost

l = kilo of lobster

Second restaurant price: 41 + 3l = x

We want them to be the same price, so: 29 + 6l = 41 + 3l

Subtract 3l from each side

29 + 3l = 41

Subtract 29 from both sides

3l = 12

Divide both sides by 3

l = 4

So, if she buys 4 kilograms of lobster from either place, it will cost the same.

It would cost $53.
