13. Robert and Adam each own a candy shop. Robert has 203 Red Starburst and 170 Green Starburst. Robert has 60 more than Adan in his candy shop. Create an equation that can be used, that can be find the number of Starburst, \( s \), Adam has in his shop.

1.1.1 \( x=\frac{4}{x}+3 \)

Evaluate the following function. Your answer should be an integer. \( f(x)=-3^{2 x-2} \), for \( x=3 \) Your answer is \( f(3)=\square \)
