Final answer:
The equation to represent the total cost c that Linda pays for buying p pounds of chocolate is c = 6p.
Step-by-step explanation:
To represent the total cost that Linda pays for buying p pounds of chocolate, we can use the equation:
c = 6p
This equation shows that the cost c is equal to 6 times the number of pounds p that Linda buys. For example, if Linda buys 2 pounds of chocolate, the total cost would be 6 multiplied by 2, which is $12.
