A 6-kilogram bag of rice costs $3.80. What is the unit price, rounded to the nearest cent?
iragen [17]

Answer:

The unit price is <u>63 cent</u> per kilogram bag of rice.

Step-by-step explanation:

Given:

A 6-kilogram bag of rice costs $3.80.

Now, to find the unit price.

So, to get the unit price we use unitary method:

If cost of 6 kilogram bag of rice = $3.80.

Then cost of 1 kilogram bag of rice = \frac{3.80}{6}  = \$0.633.

Thus, the unit price is $0.633 per kilogram bag of rice.

Now, according to question we convert the unit price into cent by using conversion factor:

$1 = 100 cent

$0.633 = 0.633\times 100=63.3\ cent.

<em>So, rounded to nearest cent  = 63 cent.</em>

Therefore, the unit price is 63 cent per kilogram bag of rice.
