Hello :
f(x) = (2x-5)/3
<span>f−1(x) = (3x+5)/2
because : f(x) 0 </span>f−1(x) = x and f−1(x) 0 f(x) = x
f(x) 0 f−1(x) = f( f−1(x) ) = f ((3x+5)/2) = (2(3x+5)/2 - 5))/3 = 3x /3 =x

$0.05x+0.085y=40
$
Multiply both sides of second equation by 20 to get $x+1.7y=800$
Subtract that from first equation to get $0.7y=300$
Divide both sides by 0.7 to get $y=428.571$ , so about $428.57 was spent in store. This leaves $500-428.57=$71.43$ that was spent online
