How much money does Marco have? ** Half of what Marco has is $24 / 2 = $<<24/2=12>>12.
How much money does Mary have? ** If he gives Mary $12, she has $12 + $15 = $<<12+15=27>>27.
How much more money does Mary have than Marco? ** Now subtract the money Mary spends: $27 - $5 = $<<27-5=22>>22.
How much more money does Mary have than Marco? ** Now subtract Marco's money from Mary's remaining money, $22 - $12 = $<<22-12=10>>10.
