One cookie costs $0.20 and one drink costs $1.65

=========

Let D represent the cost of a drink and C represent the cost of a cookie.

Set up equations based on given details.

From Juan's purchase:

  • D + 2C = $2.05

From Keisha's purchase:

  • D + C = $1.85

Subtract the second equation from the first to find the cost of one cookie:

  • D + 2C - (D + C) = $2.05 - $1.85
  • C = $0.20 (cost of one cookie)

Substitute the value of C into Keisha's equation to find D:

  • D + $0.20 = $1.85
  • D = $1.85 - $0.20
  • D = $1.65 (cost of one drink)
