to find the inverse of the function exchange x and y and then solve for y
y = 5 / sqrt (x)
x = 5 / sqrt(y)
multiply by the sqrt(y)
x * sqrt(y) = 5
divide by x
sqrt(y) = 5/x
square both sides
y = (5/x) ^2
y = 25/x^2
The inverse of 5 / sqrt (x) is 25/x^2
White chocolates
$4.50 x (2/3)
= $9/3
= $3
Gummy bears
$2.40 x (1/2)
= $2.40/2
= $1.20
Dark chocolates
$6.00 x (1 1/4)
= $6.00 6/4
= $7.50
$3.00 + $1.20 + $7.50
=$11.70
Therefore, Victor spent $11.70 on candy for the party.
