Nick bought a pair of glasses for $200. He later saw the same glasses advertised for 20% less than what he originally paid. What
price were the glasses being advertised for?
2 answers:
$160
.20 * 200= 40
200-40=160
(original-new) / original = discount
(200-new)/200 = .20
multiply by 200 on both sides
200 - new=40
subtract 200 from each side
-new = -160
multiply by -1
new = 160
the selling price is $160

Answer:
y=55x
given y=385
x=gallons of gas = 385/55 = 7 gallons
inverse function
y=55x
change x to y and y to x
x=55y
y=x/55
inverse function is x/55
