A shop charges a fixed delivery fee of 26 taka plus 6 taka for each eraser pack. If the total cost is 80 taka, how many eraser packs were ordered?
Note
Let x be the number of items. The equation is 26 + 6x = 80. Subtract 26: 6x = 54. Divide by 6, so x = 9. The fixed fee is not part of the item count.
