Jeremiah takes a taxi home from the mall. The taxi company charges $3.00 as an initial cost to pick him up, and $2.50 for every mile to his destination. Jeremiah’s ride home cost a total of $24.25. Enter an equation to represent the situation. Let m represent the number of miles to his house.

A gardener buys a rake and a pair of gloves for each of the 12 volunteers in the gardening club. Each pair of gloves cost $8.00. The gardener spends a total of $300 on both rakes and gloves. Enter an equation that models the situation with r, the cost of 1 rake. (2 answers)

• 12 (r + 8) = 300

• 12r + 96 = 300

• 12r + 8 = 300
