In a nursery, one stalk of rose costs 1.5 times the price of one stalk of daisy.
Janice bought 2 stalks of roses and 3 stalks of daisies. Brenda bought
6 stalks of daisies. Both girls paid the same amount for their flowers.
a) Write a linear equation to find the cost of each stalk of daisies
Let
x -----> the price of one stalk of rose
y ----> the price of one stalk of daisy
we have that
x=1.5 y -------> equation A
Janice
2x+3y
Brenda
6y
we have that
Both girls paid the same amount for their flowers
so
2x+3y=6y
2x=3y ----> equation B
substitute equation A in equation B
2(1.5y)=3y
3y=3y
or
3d=3d ------> it's an identity
the system has inifinite solution
Part b)
the equation is an identity
Part 2
we have that
distance floor to the ceiling --------> 12.5 ft
