Answer:

At the 3rd day 160 students caught flu.

Step-by-step explanation:

Consider the provided model P = − t ² + 13t + 130 where 1 ≤ t ≤ 6

The total number of students is represents by P.

We need to find the day that 160 students had the flu.

Substitute the value of P=160 in above formula.

$160 = -t^2 + 13t + 130$

$160+t^2 - 13t - 130=0$

$t^2 - 13t +30=0$

$t^2 - 10t-3t +30=0$

$t(t-10)-3(t-10)=0$

$(t-10)(t-3)=0$

Hence the value of t=10 or t=3

But it is given that 1 ≤ t ≤ 6, Therefore select t=3

Hence, at the 3rd day 160 students caught flu.
