Show you know
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.
