### Guided Practice

• Question 1
Isaiah is buying jelly beans. In bulk, they cost $3 per pound, and a candy dish costs$2. The function rule, 3x + 2 where x is the number of pounds, can be used to find the total cost of x pounds of jelly beans and 1 dish. Make a table that shows the total cost of buying 2, 3, or 4 pounds of jelly beans and 1 dish. • Question 2

Jasper hikes 4 miles per hour. The function rule that represents this situation is 4x, where x is the number of hours. Make a table to find how many hours he has hiked when he has gone 8, 12, and 20 miles. Then graph the function. • Question 3
