We want to find out low long it will take for A to become half of its original amount.
We don't know the original amount, and the substance is not decaying at a constant rate (but rather an exponential one) so we can't answer that question.

Answer:
an=7.35+ 0.33(n-1)
Step-by-step explanation:
The relationship between women's whole-number shoe sizes and foot lengths is an arithmetic sequence, where an is the foot length in inches that corresponds to a shoe size of n.
We are given values for n=7 and n=12 as a7=9.33 and a12=11
So, we proceed from the options and check which an satisfies these values:
an = 7.35 + 0.33(n-1)
when n = 7:
an = 7.35 + 0.33 (7-1)
an = 9.33
when n = 12:
an = 7.35 + 0.33 (12-1)
an = 10.98≈11
Hence, correct option is:
an=7.35+ 0.33(n-1)
