One box of pop tarts costs 1.73 dollars. If purchasing more than 10 boxes, each box costs 1.53 dollars. How many dollars are saved by purchasing 54 boxes of pop tarts all at once rather than one at a time?

Question

More than 10 boxes refer to 11 boxes right? So, is it okay if I multiply 43 (54-11) boxes with $1.53?

Um, I would multiply 1.53 by 54 and subtract the answer from 1.73 multiplied by 54...

Why? I didn't understand.

If more than 10 boxes are purchased at a time, then the price is no longer 1.73 each, but rather 1.53 each.
So if 54 boxes were bought, at each one at different times, then the total price would be 1.73 x 64, 93.42. But if 54 boxes were bought all at the same time, the total price would be 1.53 x 54, 82.62.
