What is unitary method?
"It is a method of finding the value of a single unit, and based on this value we can find the required value."
For given question,
Let 'm' be the cost of a single shirt.
There are seven players in the team.
The total value of the order is $89.60.
⇒ 7 × m = $89.60
By unitary method we find the cost of single shirt.
⇒ 7 × m = 89.60
⇒ m = 12.8
This means, the cost of one shirt is $12.8
At the last minute she orders three extra shirts for the reserve players.
By unitary method we find the cost of three extra shirts.
The cost of three extra shirts would be,
⇒ 3 × m
= 3 × 12.8
= 38.4
So, the cost of three extra shirts = $38.4
Now, the total value of the order is,
$89.60 + $38.4 = $128
Therefore, the total value of the order would be $128
