The cutty sark is a famous clipper ship (look it up)! a cutty sark model kit advertises a scale ratio of 1: 78, a length of 45 inches, and a height of 26 inches.
a. how long was the cutty sark, according to this model kit?
b. how tall was the cutty sark, according to this model kit?

A. Cutty Sark length is 3510

B. Cutty Sark height is 2028

Step-by-step explanation:

The ratio represents how many units are of one kind every another kind.  

In this case , a Cutty Sark model kit advertises a scale ratio of 1: 78, that means that this model is 78 time smaller that the real ship. So if the model has  a length of 45 inches, and a height of 26 inches,  the Cutty Sark is 78 times bigger.  We get the real measures multiplying the length and height of the model by 78.

Cutty Sark length=45 inches x 78=3510

Cutty Sark height=26 inches x 78=2028

to determine the unit cost your would divide the total cost by the number sold.
