Ella bought 8 meters of ribbon for $10.

Zanzabum

Answer:

$0.03 per inch

Step-by-step explanation:

We need to convert 8 meters to inches first.

Unit ratio for meters to cm is:

$\frac{1m}{100cm}$

So 8 meters is 800 cm

Now,

we need to convert 800 cm to inches

Unit ratio for cm to inches is:

$\frac{2.54cm}{1inch}$

So, 800 cm is :

$\frac{800}{2.54}=314.96$ inches

To get costing per inch, we divide total cost ($10) by the total number of inches (which is 314.96):

$\frac{10}{314.96}=0.032$

Rounded to nearest hundredth, $0.03 per inch
