Given:
A 12 oz package of cheese costs $ 1.38 How much does 1 Lb of the same cheese cost?
First, we will convert from Lb to an ounce
so,
1 Lb = 16 ounces
Using the ratio and proportions
Weight : Price
12 oz : $1.38
16 oz : x
So, we will find x as follows using the cross product
![x=(16)/(12)*1.38=1.84](https://img.qammunity.org/2023/formulas/mathematics/college/58lqrcqxos6ofdguv990ss5dvxuuip9avm.png)
So, the answer will be:
