She'll be on vacation for 40 days and drinks 3 cups of coffee/pods per day for a total of 40*3 = <<40*3=120>>120 coffee pods
Her coffee pods come 30 in a box and she needs 120 coffee pods so that’s 120/30 = <<120/30=4>>4 boxes
Each box costs $8.00 and she needs 4 boxes so that’s 8*4 = $<<8*4=32.00>>32.00
