Answer:
$39.36
Step-by-step explanation:
The first sale we saw, which was 20% off, needs to be applied first as the second discount is additional. With that being said, we need to multiply 82 times 80%. This is because we removed 20% of the standard 100% amount and we are left with 80%. To convert this, keep in mind 100% is equal to 1. So 80% is equal to .80 with this logic. So 82x0.8=65.6. Now we need to take 40% off of the modified price 65.6. By converting 40% off is equal to 0.60(keyword off). Now 65.6x0.60=39.36. The final price is 39.36

Associative property:

Step-by-step explanation:
7y = 9x-27
sub 7x = 9x-27 into 2nd eqn
45 + (9x-27) = 9x
move 9x over
18 = 9x - 9x
18 = 0
this doesn't make sense, so eqn has no solution
