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? Let's answer step by step:
Ten shirts cost 10 x $5 = $50. And, three pairs of sandals cost 3 x $3 = $9. Thus, she spent $50 + $9 = $59. Therefore, she got back change of $100 - $59 = $41. The answer: 41.
