"In Store A, a book that regularly sells for $24.99 is on sale at 15% off. In Store B the same book regularly sells for $27.99 and is on sale at 25% off. Which store sells the book for the lower sale price?"
"the choises are A Store A; Store A’s sale price is $18.74 and Store B’s sale price is $23.79. B Store A; Store A’s sale price is $18.74 and Store B’s sale price is $20.99.

15% of 24.99 is 3.7485.
24.99 - 3.7485 = 21.2415
25% of 27.99 is 6.9975
27.99 - 6.9975 = 20.9925

<em><u>We should add another 12 until we get to 120. </u></em>
<em><u>108+12=120. That is 10 times. The trick was...</u></em>
<em><u>dividing by 12 is hard, so lets say 12x4. I can put 4 and 4 together.</u></em>
<em><u>44 then and another 4. That is 48. So 12x4=48.</u></em>
