The Equations and Inequalities: The Properties of the Equality Relation in N and Z

Mustafa buys three chocolate bars and checks the receipt to find the price of each. The total cost is 10 lbs, with the caramel chocolate priced at 4 lbs. Maggot, a math genius, calculates the price of each white chocolate bar as 3 lbs using basic algebra. The video encourages viewers to solve similar equations and practice their math skills.

What was the total cost of the chocolate bars that Mustafa bought?

• 15 lbs

• 12 lbs

• 10 lbs

• 8 lbs

How much did the caramel chocolate bar cost according to the receipt?

• 5 lbs
