Answer:

Equation : 100 + (n - 20) × 3.5 = 345

90 students went for tour.

Step-by-step explanation:

Since, the cost of first 20 students is fix and it is $100

and, each student after these 20 students has to pay $3.50, also tour cost is $345.

Let the number of total student went for tour be "n".

Hence, we get equation,

100 + (n - 20) × 3.5 = 345

⇒  (n - 20) × 3.5 = 345 - 100

⇒  (n - 20) × 3.5 = 245

⇒  (n - 20) = 245 ÷ 3.5

⇒  (n - 20) = 70

⇒ n = 90 students

The total paid was $345.  Twenty students cost $100.00.  $345-4100=$245
245/3.50=70 additional students.  70+20=90 students went on the tour

<span><span>f<span>(x)</span></span>=<span>(x−6)</span><span>(x+5)</span><span>(x−9)</span></span>

If all of the linear factors are non-zero, then so is their product <span>f<span>(x)</span></span>.

If any of the linear factors is zero, then so is their product <span>f<span>(x)</span></span>.
