Question

An orange costs $\$ 0.09.$ How much would $2$ a dozen oranges cost?

Answer 1

Hint: Here in this question they have given the cost for a single orange as $\$ 0.09$ and asked us to find out how much it would cost for $2$ dozen of oranges. We know that there will be $12$ oranges for $1$ dozen, in the same way, multiply it for $2$ dozen of oranges, which then multiply by $\$ 0.09$ to get the required cost for $2$ dozens of oranges.

Complete step by step answer:
In the given question they have given the cost for a single orange as $ 0.09$ dollars and asking us to find out how much it would cost for $2$ dozen of oranges.
First, we need to know many oranges will be there in $2$ dozen. Before we do two dozen, we know that there will be $12$ oranges in $1$ dozen, in the same way, multiply it for $2$ dozen of oranges.
Therefore, if $1dozen = 12oranges$, then for two dozen we have
$2dozen = 2 \times 12oranges$
$ \Rightarrow 2dozen = 24oranges$
Now we know that two dozen are having $24$ oranges, if the cost of one orange is $\$ 0.09$, we need to calculate how much it would cost for $24$ oranges.
Therefore, we multiply $24$ with $\$ 0.09$ to get the cost of $2$ dozen oranges.
Cost of $2$ dozen oranges $ = 24 \times 0.09\$ $
$ = 2.16\$ $ or $\$ 2.16$ (dollars)

Hence the $2$ dozen orange costs $\$ 2.16$.

Note:
The above problem can be solved in another way also, that is first if we know one dozen is consisting of $12$ oranges, then find the value it costs for one dozen oranges. The result or the cost we got for one dozen is then multiplied by two to get the required answer.
