Answer:
B ) The number of cans produce in 25 minutes is 104
C) The cost of 3 pens is $1.2
Step-by-step explanation:
Given as :
B) The number of cans produce every hour = 250
Let The number of cans produce in 25 minutes = x
Applying The unitary method
∵ 1 hour = 60 minutes
∵ The number of cans produce in 60 minutes = 250
So, The number of cans produce in 1 minute = [tex]\frac{250}{60}[/tex]
∴ The number of cans produce in 25 minutes = [tex]\frac{250}{60}[/tex] × 25
Or, x = 104.167
Or, x ≈ 104
Hence, The number of cans produce in 25 minutes is 104 . Answer
C) The cost of 14 pens = $5.60
Let The cost of 3 pens = y
Applying unitary method
∵ The cost of 14 pens = $5.60
So, The cost of 1 pen = [tex]\frac{5.60}{14}[/tex]
∴ The cost of 3 pens = [tex]\frac{5.60}{14}[/tex] × 3
i.e y = [tex]\frac{5.60}{14}[/tex] × 3
Or, y = $1.2
Hence, The cost of 3 pens is $1.2 Answer
