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.

• 12(r+8)=300

• 12r - 12(8.00) = 300

• r + 12(8.00) = 300

• 12r * 8.00 = 300
