3/2z+3/2

Explanation:

50%=1/2

Let s be such an expression that s=50% of 1/20 of the product of 12 and 5z+5

s=1/2(1/20(12(5z+5)))
=1/2(1/20(60z+60))
=1/2(3z+3)
=3/2(z+1)

Personally you can leave it there; it is factored into 1 set of brackets with integers inside the brackets, although likely the question wants you to expand the brackets fully.

s=3/2z+3/2
