A pound of chocolate costs 7 dollars. Tony buys \( p \) pounds. Write an equation to represent the total cost \( c \) that Tony pays.

The total cost \( c \) that Tony pays can be represented by the equation \( c = 7p \). In this equation, \( 7 \) represents the cost per pound of chocolate, and \( p \) is the number of pounds Tony buys. So, the more pounds he buys, the higher the total cost! Now imagine if Tony decides to go big and buy 10 pounds. He'd be looking at a sweet total of \( 7 \times 10 = 70 \) dollars—definitely a chocoholic moment!
