Question

Answer 1

Given:

Granny Apples charge $12 for 6 pounds of apples.

Wilson' Apples charges $15 for 5 pounds of apples.

To find:

Which apple company provides a better deal.

Solution:

We need to compare unit price of both companies.

$\text{Unit price}=\dfrac{\text{Total price}}{\text{Number of units}}$

Unit price of Granny Apples,

$\text{Unit price}=\dfrac{\ 12}{6}$

$\text{Unit price}=\ 2$

Unit price of Wilson Apples,

$\text{Unit price}=\dfrac{\ 15}{5}$

$\text{Unit price}=\ 3$

Since, per unit price of Granny Apples is less than Wilson Apples, therefore Granny Apples provides a better deal.
