Question

Use Dimensional Analysis

Answer 1

Hello Gavin

 

First we need to convert the price of saffron from $ per oz to $ per grams.  The conversion factor is:

 

1 oz = 28.3 g

 

($368 / 1 oz) x (1 oz / 28.3 g) = $13.00 / g

 

Now setup a proportion to solve for the # of grams you can purchase for $15.00.

 

1 g = $13.00

 

? g = $15.00

 

# of grams = ($15.00 x 1 g) / $13.00 = 1.15 grams
