Question 363787
100% represents the total cost of the PS2.

Since $68 represents 35% of the total cost of the PS2, we divide 100% by 35%.

Disregard the % sign first.

So 100/35 = 2.857

Now we mulitply this to $68

And we now get $194.285 or simply $194.29.

To find Ken's contribution which is 27% of the total cost, we get the 27% of $194.29.

194.29*(27% or 0.27) = 52.458 or $52.46
