So first you would do 10 x 1.5 to find how much money Daisy gets paid after working for more than 8 hours.
10 x 1.5 = 15
She gets paid $15/hour after working for 8 hours
If Daisy works for 13 hours then all you have to do is do, 13-8 = 5
8 x 10 = $80 and then those 5 extra hours she worked, she earned $15/hour
15 x 5 = $75
$80 + $75 = $155
