cost

$3.50

Explanation:

Step1: Identify the cost per pound

The cost per pound of gummy bears is $3.50, so for \( n \) pounds, the cost \( C \) is given by the formula \( C = 3.50\times n \).

Step2: Calculate the cost for 19 pounds

We need to find the cost for \( n = 19 \) pounds. Substitute \( n = 19 \) into the formula: \( C = 3.50\times19 \).
Calculate \( 3.50\times19 \):
First, \( 3\times19 = 57 \) and \( 0.50\times19 = 9.50 \). Then add them together: \( 57 + 9.50 = 66.50 \).

Answer:

For 19 pounds of gummy bears, the cost is $66.50. So the table should be filled as:
