A = P.e^(r.t), where P is the initial population, r = rate of growth , 
t = interval of time & e = 2.7182...

A = 524(2.7182...)^(0.07x7) = 855.33 ≈ 856

Answer:

781

Step-by-step explanation:

524/.07=36.68

36.68 is 7% of `524 so

36.68*7=256.76

then you add the total bacteria to that number and you get 780.76. but because it's round to the nearest whole number it's 781.
