Original price- $10.00

store a) 50% off

$10.00 divide by 2 = $5.00

Price- $5.00

store b) 25% off one day followed by 25% off reduced price the second day.

$10.00 divide by 4 = 2$2.50 $10.00 - $2.50 = $7.50

$7.50 divide by 4 = $ 1.857

$7.50 - $1. 857 = $5.643

Price- $ 5.643

I think store a is a better deal because it is much cheaper rather than paying more than 50 cents more.
