Danny earns income equal to 50% of his sales minus the shipping cost of his products. He wants his income to be at least $1,400 this month and calculates that his total shipping cost will be $32. This can be represented by the inequality 0.5x - 32 ≥ 1,400, where x represents the amount of his sales in dollars. What is the least amount of sales Danny must have to ensure that his income is at least $1,400 this month?

• $3200

• $2864

• $3000

• $2500
