Introduction

Jan is a busy shopper who wants to calculate the total cost of her shopping cart. She has two items: oranges and flour. Each item has a price and a discount percentage. In this article, we will guide Jan through the process of calculating the total cost of her shopping cart, taking into account the discounts on each item.

Understanding the Shopping Cart

Jan's shopping cart contains two items:

Oranges: priced at $1.36 per unit, with a 25% discount
Flour: priced at $4.39 per unit, with an 18% discount

Calculating the Discount on Oranges

To calculate the discount on oranges, we need to multiply the price of oranges by the discount percentage.

Price of oranges: $1.36
Discount percentage: 25%

Discount on oranges = Price of oranges \* Discount percentage
= $1.36 \* 0.25
= $0.34

Calculating the Discount on Flour

To calculate the discount on flour, we need to multiply the price of flour by the discount percentage.

Price of flour: $4.39
Discount percentage: 18%

Discount on flour = Price of flour \* Discount percentage
= $4.39 \* 0.18
= $0.79

Calculating the Total Cost of Oranges

To calculate the total cost of oranges, we need to subtract the discount from the price of oranges.

Price of oranges: $1.36
Discount on oranges: $0.34

Total cost of oranges = Price of oranges - Discount on oranges
= $1.36 - $0.34
= $1.02

Calculating the Total Cost of Flour

To calculate the total cost of flour, we need to subtract the discount from the price of flour.

Price of flour: $4.39
Discount on flour: $0.79

Total cost of flour = Price of flour - Discount on flour
= $4.39 - $0.79
= $3.60

Calculating the Total Cost of the Shopping Cart

To calculate the total cost of the shopping cart, we need to add the total cost of oranges and the total cost of flour.

Total cost of oranges: $1.02
Total cost of flour: $3.60

Total cost of shopping cart = Total cost of oranges + Total cost of flour
= $1.02 + $3.60
= $4.62
