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

The equation to represent the total cost c that Ahmad pays is:

c = 7p

The equation that represents the total cost c that Ahmad pays is:

c = 7p

To represent the total cost, c, that Ahmad pays when buying p pounds of chocolate, we can multiply the cost per pound, which is 7 dollars, by the number of pounds, p. This gives us the equation:

c = 7p

In this equation, c represents the total cost and p represents the number of pounds of chocolate Ahmad buys.
