" · " - times
" + " - sum
n - a number
0.5n - half a number
10 · (0.5n + 6) = 8 |use distributive property
(10)(0.5n) + (10)(6) = 8
5n + 60 = 8 |substract 60 from both sides
5n = -52 |divide both sides by 5
n = -10.4
The answer is C) 3 x 10^4
See attachment for answer:
for every 1 person that has the flu then 6 have flu like symptoms
if the doctor has 40 patients then lets guess and check
if 5 people have the flu then 30 have the flu like symptoms and that is 35 so no
and if 6 had the flu then there would be 36 people with flu like symptoms
so there should be from 30-36 people with ONLY flu like symptoms
