Final answer:
The function c(p) represents the cost of p pounds of cantaloupes at $4.50 per pound, so c(p) = 4.50 × p.
Step-by-step explanation:
To represent the cost for the number of pounds of cantaloupes bought, p, using a function, we can define a function c(p). Given that the price of cantaloupes is $4.50 per pound, the function would simply be the number of pounds multiplied by the price per pound. Therefore, the function is c(p) = 4.50 × p. For example, if you bought 2 pounds of cantaloupes, the cost would be c(2) = 4.50 × 2 = $9.00.
