Since Irina is only willing to pay 20 cents less for each subsequent glass, there will be a maximum of 12 glasses she would be willing to pay for (given that she is unwilling to pay negative amounts for juice). The maximum amount she would be willing to pay for each glass is as follows: $2.40, $2.20, $2.00, $1.80, $1.60, $1.40, $1.20, $1.00, $0.80, $0.60, $0.40, and $0.20. Therefore, she would be willing to drink a total of 13 glasses (including the first glass she would pay $2.40 for) before deciding it is no longer worth the cost.
