You just keep subtracting 3 yo the previous number, so day one would be $82 and day three would be $79...etc. Day five would be $70 so sweet

Answer:
$50.
Step-by-step explanation:
Let the full price be x dollars, then:
x - 0.20x = 40
0.80x = 40
x = 40/0.80
x = 50.
We can use ratio
If the person works for 12 hours and earns $510, for one hour:
12*1=510*x
x=510/12
x= $42.5
Thus the person earns 42.5 dollars per hour.
