Question

find the cost of 18 bananas at rate of $4 per dozen

Answer 1

Given,

The cost of the dozen bananas is $4$

$1$ dozen $= 12$

So, cost of one banana $=\frac{4}{12}$

Cost of one banana  $=0.333$

Cost of $18$ bananas $=18\times0.333$

Cost of $18$ bananas $=5.999\cong 6$

Therefore, the cost of $18$ bananas is $6$.

Answer 2

Answer:

$\ 6$

Step-by-step explanation:

Given data

• Cost of dozen bananas $=\ 4$

• $1$ dozen $=12$ items

• 18 bananas $=\frac{18}{12}$ dozens

Now, cost of $18$ bananas $=\frac{18}{12}\times4=\ 6$

Hence, the cost of $18$ bananas is $\ 6$.
