I'm not really sure how to even begin this problem? Help would be deeply appreciated! Thanks in advanced

Simply replace t by 70:

$${\mathtt{y}} = {\mathtt{40}}{\mathtt{\,\times\,}}{\left({\frac{{\mathtt{1}}}{{\mathtt{2}}}}\right)}^{\left({\frac{{\mathtt{70}}}{{\mathtt{40}}}}\right)} \Rightarrow {\mathtt{y}} = {\mathtt{11.892\: \!071\: \!150\: \!027\: \!210\: \!7}}$$

y = 11.89 grams to the nearest one-hundredth of a gram
