jdoe0001 · Answer

0.5 cup is the same as $\bf \cfrac{1}{2}$    so $\bf \cfrac{1}{2}\ cup $   is 64grams, so to make 1 cup you'd need twice as much, or 64 + 64 = 128

thus in 1cup there are 128gms

g(x) = 128 x

x = cups

let's check that, let's find out how many grams in 2cups

$\bf g(x) = 128x \implies g(x) = 128(2) \implies g(x) = 256$

256 grams per 2 cups
