Solution:
Given that, 2 pounds of carrots cost $1.59,
then , to find the cost of 7 pound carrots, solve it by unitary method,
first calculate the cost of 1 pound carrot.
2 pound costs $1.59
then, 1 pound will cost [tex] \frac{1.59}{2} [/tex]
Now , Multiply 7 to the cost of 1 pound carrot to get the cost of 7 pound carrot
[tex] = 7*\frac{1.59}{2}= \frac{1119}{200} = 5.56 [/tex]
Hence, If 2 pounds of carrots cost $1.59,then 7 pounds of carrots would cost $5.56
