Answer:
$2.70
Step-by-step explanation:
Divide $2.10 by 7 to find unit cost and multiply this by 9, that is
cost of 9 = [tex]\frac{2.10}{7}[/tex] × 9 = $0.30 × 9 = $2.70
Answer:
$ 2.7 will be cost of Nine
Step-by-step explanation:
Given that:
Seven (pieces) cost: $2.10
From the cost of seven pieces ($210), we will first find the cost of one piece by dividing the cost ($210) by 7
So,
One (piece) cost= $(2.10/7)
One (piece) cost= $0.3
Now after obtaining the cost of one piece, The cost of nine pieces can be obtained by multiplying the cost of one piece with 9 as follows:
Nine (pieces) cost = $(9*0.3)
Nine (pieces) cost = $2.7
So the 9 pieces will cost $2.7
