Question

during an experiment the number of bacteria increased at a rate of 1.5% in a year if the initial of bacteria was 2365 find the number of bacteria after 2 years​ (with intermediate steps)

Answer 1

Answer:

2435.95

Step-by-step explanation:

$number \: of \: bacteria \: = 2365$

$rate \: of \: bacteria \: increasing = 1.5\% \:p er \: year$

$no. \: of \: years = 2$

$no. \: of \: bacteria \: increased = \frac{2365 \times 1.5 \times 2}{100}$

$= \frac{2365 \times 15 \times 2}{10 \times 100}$

$= \frac{70950}{1000}$

$= 70.95$

$total \: bacteria \: after \: 2 \: years = 2365 + 70.95$

$= 2435.95$

Therefore, total number of bacteria is 2435.95
