I'm a little confused as to how you wrote out each of the equations, but if there are 2 ounces of fruit cremes, and the box weighs 8 ounces, then there would be 6 ounces of caramels in the box.
Lin's tour costs 5*14 +50 = 70 +50 = 120. Max's tour costs 120.
Neither tour costs less. Both have the same cost.
754x78%=588.12
You can't have 0.12 of a person so in this case, you would round up
The answer is roughly 589
use the Pythagoras theorem method
a squared plus b squared equals c square
