Yanna bought ten shirts at $5 each and three pairs of sandals at $3 each.  How much change did she get back if she gave a one hundred dollar bill?
Ten shirts cost 10 x $5 = $<<10*5=50>>50.
And, three pairs of sandals cost 3 x $3 = $<<3*3=9>>9.
Thus, she spent $50 + $9= $<<50+9=59>>59.
Therefore, she got back change of $100 - $59 = $<<100-59=41>>41.
