Question 1126730
We can start with $50 as the price as of Monday, before the reduction. <br>

30% of $50 is  0.30*$50 = $15, so the price after reduction is  $50-$15 = {{{ highlight( matrix(1,2, "$", 35) ) }}}<br>

Alternate solution:  30% off means final price is 70% of Monday's starting price:  0.7*$50 = {{{  matrix(1,2, "$", 35)  }}}<br>
