Question 1161069: The spread of a Virus. The number of MRSA (methicillin-resistant Staphylococcus aureus) cases has been rising sharply in England and Wales since 1997. In 1997,4060 cases were reported. The number of cases reported in 2003 was 7455 . How many cases will be expected in 2011? (Let=0 correspond to 1997.) Use the formula N=Noe^(rt), where N represents the number of cases reported.
Round to the nearest case. (Use rounded to two decimal places in the calculation.)reported cases in 2011.
please solve

MRSA is a bacterium, NOT a virus. People need to understand the difference, and your teacher should know this. Why? For one, viruses are not treatable by taking antibiotics, as those only work for bacterial infections.
Yes, sometimes when a virus has infected a person, a doctor will prescribe antibiotics as a protective measure against secondary bacterial infections, but that is not to treat the primary viral infection.

t=0 for 1997 ===>

Use the 2003 data to find r (in 2003, t=6 yrs):

So we have the full equation:

For 2011, t=14:
=
