Answer:
25 silk leaves
Step-by-step explanation:
The opportunity cost would be what was normally stopped by doing something else, we have two scenarios:
First stage:
A combination of 60 silk roses and 80 silk leaves
Second stage:
A combination of 70 silk roses and 55 silk leaves
Therefore, comparing the two scenarios, by producing more silk roses, the amount of silk leaves is decreased, by the following amount:
80 silk leaves - 55 silk leaves = 25 silk leaves.
Therefore the opportunity cost is 25 silk leaves

Step-by-step explanation:
thats already answerded
The number is xy
x+y=12
10y+x=54+10x+y
so
x+y=12
minus x both sides
y=12-x
sub that for y
10(12-x)+x=54+10x+(12-x)
120-10x+x=54+10x+12-x
120-9x=66+9x
add 9x both sides
120=66+18x
minus 66 both sides
54=18x
divide both sides by 18
3=x
sub back
y=12-x
y=12-3
y=9
the number is 39
