Answer
The number of roses sold for every 2 lilies sold are: 7
Explanation:
It is given that:
A flower shop sold 3.5 times as many roses as lilies last week.
This means that if r is the number of roses sold.
and l is the number of lilies sold.
Then,
r=3.5 l
Now, we are asked to find the number of roses sold if the number of lilies sold are 2.
i.e. we are asked to find the value of r if l=2
Hence on putting l=2 in equation (1) we have:
r=3.5×2
i.e. r=7
This means that the number of roses sold when 2 lilies are sold= 7
