Use the rule of logarithms:
log(a)-log(b)=log(a/b)
log(65--log(x)=log(39)=log(65/x)
=> 39=65/x =>
x=65/39=5/3
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.

So you have 175 guests. = 175gst
1 cheeseck= 12 gst
Set up you ratio so that your units cancel.
175gst x 1 cheese c
----------------
12 gst
Here the gst cancel and you are left with cheese cake so
175/12 = 14.58 or 15
