Mobile - $129 1/10 of 129= 12.9 so 3/10 of 129 is 38.7 So you would get $38.70c off 129 = $90.30c 30% off 129 would make the total cost $90.30c √

External hard drive - $129 1/10 of 129= 12.9 so 3/10 of 129 is 38.7 So you would get $38.70c off 129 = $90.30c 30% off 129 would make the total cost $90.30c √

Printer- $149 1/10 of 149 = 14.9 so 3/10 of 149= 44.7 So you would get $44.70c off 149 = $104.30c 30% off 149 would make the total cost $104.30c

Camera - $199 1/10 of 199=19.9 so 3/10 of 199= 59.7 So you would get $59.70c off 199 = $139.30c 30% off 199 would make the total cost $139.30c

Theatre system - $249 1/10 of 249 = 24.9 so 3/10 of 249 = 74.7 So you would get $74.70c off 249 = $174.30c 30% off 249 would make the total cost $174.70c
