Question

The flu is starting to hit Weston. Currently, there are 380 people infected, and that number is growing at a rate of 15% per day. Overall, how many people will have gotten the flu in 7 days? If necessary, round your answer to the nearest whole number.

Answer 1

1011 or 1010, depending on how you round. (I got 1011)

Step-by-step explanation:

we need to calculate 15% of the non-constant x seven times.

x starts as 380.

15%=0.15

15% of x seven times:

380*0.15=57,

380+57=437;

437*0.15= 65.55,

437+65.55= 502.55;

502.55*0.15=75.38,

502.55+75.38=577.93;

577.93*0.15=86.69,

577.93+86.69=664.62;

664.62*0.15=99.69,

664.62+99.69=764.31;

764.31*0.15=114.65,

764.31+114.65=878.96;

878.96*0.15=131.84

878.96+131.84= 1011
