E. None of the above


$1 = 8.5/12 of what we'd need for a gazoo.

100 gazoos * 12/8.5 = 1200/8.5 = 141

Answer choice D.

Not silly at all...would be silly if you didn't understand and decided NOT to ask!! :)

$1 gets us 8 grotniks and 8 kronkheits.

12 grotniks gets us a gazoo. We have 8 grotniks plus enough kronkheits to get half of another grotnik. So we have 8.5 of the 12 grotniks required to get a gazoo. 8.5/12

question says It takes 16 kronkheits to make a grotnik so (8 kronkheits is one-half of a grotnik)
$1 can be exchanged for 8 grotniks and 8 kronkheits, or say 8.5 grotniks

E. None of the above




Given: $1= 8 grotniks + 8 kronkheits
16 kronkheits= 1 grotniks
12 grotniks= 1 gazoo

for 100 gazoo

1 gazoo =12 grotniks
100 gazoo = 1200 grotniks


$1=8.5 grotniks
therefore 1200/8.5= 141.18
