Answer:

821 bacteria

Step-by-step explanation:

You have that the growth of bacteria is represented by:

y = 79.31(1.48)x

N° Bacteria=79.31(1.48)(N° Days)

If you know that N° Days is 7, you need to replace x=7 in the Equation given.

Then:

N° Bacteria=79.31(1.48)(N° Days)

N° Bacteria=79.31(1.48)(7)

N° Bacteria=821,65
