Answer:
$20.23
Step-by-step explanation:
if you take 14.45 and divide it by 5 you get $2.89
which makes it 2.89 a pound. so 2.89 multiplied by 7 gets you $20.23
Given:
Turkey bought = 5 pound
Cost of 5 pound of turkey = 14.45
To find:
Cost of 7 pound of turkey
Solution:
Using unitary method, if the cost of 5 pound of turkey is 14.45 then the cost of one pound of turkey would be [tex]\frac{14.45}{5}=2.89[/tex]
Therefore, the cost of one pound of turkey is 2.89.
So, cost of 7 pound of turkey = [tex]2.89\times7=20.23[/tex]
Thus, 7 pounds of turkey costs 20.23 units.
Unitary method:
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value. In essence, this method is used to find the value of a unit from the value of a multiple, and hence the value of a multiple.
