3% is the interest so you would do 3% of the investment plus the original investment so 3%×I=z and then z+I=the answer. sorry if this didnt help I'm new and I tried my best sorry!
2% as a reduced fraction is 2/100 = 1/50
4(x + 6)
4 × x = 4x
4 × 6 = 24
3(3x + 4)
3 × 3x = 9x
3 × 4 = 12
9x + 4x = 13x
12 + 24 = 36
So your answer is B) 13x + 36. I hope this helps!
