b. How much would it cost to buy 3.5 pounds of bananas?

Answer 1

The cost of buying bananas at $0.39 a pound can be calculated using the function rule Cost = 0.39 * weight of bananas. If we want to find the cost of buying 3.5 pounds of bananas, we substitute the weight into the function.

Step-by-step explanation:

To calculate the cost of buying bananas at $0.39 a pound, we can use the function rule:

Cost = price per pound * weight of bananas

So, the function rule is Cost = 0.39 * weight of bananas.

To find how much it would cost to buy 3.5 pounds of bananas, we substitute the weight into the function:

Cost = 0.39 * 3.5

Cost = $1.365
