Answer: The required cost of 0.7 pounds of sliced meat is $7.35.
Step-by-step explanation: Given that Marcus can buy 0.3 pound of sliced meat from a deli for $3.15.
We are to find the cost of 0.7 pound of sliced meat.
We will be using the UNITARY method to solve the problem.
We have
the cost of 0.3 pound of sliced meat = $3.15.
So, the cost of 1 pound of sliced meat will be
[tex]\dfrac{3.15}{0.3}=\dfrac{31.5}{3}=\$10.5.[/tex]
Therefore, the cost of 0.7 pound of sliced meat is
[tex]10.5\times0.7=1.05\times7=\$7.35.[/tex]
Thus, the required cost of 0.7 pounds of sliced meat is $7.35.
