Question

The cost of 10 oranges is 1 dollar what is the cost of 5dozen oranges

Answer 1

For this exercise it is important to remember that:

`1dozen=12`

Therefore, to know the exact number of 5 dozen, you need to multiply 12 by 5. Then, the product is:

`12\cdot5=60`

Let be "x" the cost (in dollars) of 5 dozen oranges (or 60 oranges).

According to the information given in the exercise, you know that 10 oranges cost 1 dollars. Then, you can set up the following proportion in order to find "x":

`(1)/(10)=(x)/(60)`

Now you must solve for the variable "x". Multiplying both sides of the equation by 60, you get:

`\begin{gathered} (60)((1)/(10))=((x)/(60))(60) \\ \\ x=6 \end{gathered}`

The answer is: The cost of 5 dozen oranges is $6.00
