Let
x-------> Leila 's profit
y------> Jo's profit
we know that
----------> equation 
For 
<u>Find the value of x</u>
Substitute the value of y in the equation
therefore
<u>the answer is</u>
Leila make 
in profit
wait i got it!
Since 18 kilograms are 18000 grams, you have
18000/30=600
and
800/30=26.6
So, with 18 kilograms of salt the baker can make exactly 600 batches with no leftovers, while with 800 grams of salt the baker can make 26 batches, with some leftovers.
In fact, 26 batches require
26 x 30 =780
grams of salt, and the remaining
800-780=20
grams of salt are not enought to prepare the next batch

Step-by-step explanation:
The sum of the angles is 90
2x + x = 90
3x = 90
x = 30
the angle ABC is 2x, so it means that is the double of x, so it is 60 degrees
