Answer:
find the inverse
exchange x for y and y for x
y=2x
then
x=2y---------> clear y
y=x/2
f−1(x)=x/2

the answer is 16
Henson's cost: 3x+y=203
Garcia's cost: 2x+3y=189
Step-by-step explanation:
Given,
Cost of each adult ticket = x dollars
Cost of 3 adult ticket = 3x
Cost of 2 adult ticket = 2x
Cost of each child ticket = y dollar
Cost of 3 child ticket = 3x
Henson's cost;
3 adult tickets + 1 child ticket = $203
3x+y=203
Garcia's cost;
2 adult tickets + 3 child tickets = $189
2x+3y=189
Henson's cost: 3x+y=203
Garcia's cost: 2x+3y=189

Answer:
$356.00
Step-by-step explanation:
If d represents the discounted price, and p is the original price, you have ...
d = p - 20% × p = p(1 -20%) = 0.80p
Then the original price is ...
p = d/0.80 . . . . . divide by the coefficient of p
p = $284.80/0.80 = $356.00
The price before the discount was $356.00.
