Answer: Option B.
Step-by-step explanation:
If a varies directly with b then when a increases b it also increases by a factor k.
Then we can write that
We know that when a = 28 then b = 7. So
Therefore the equation of proportionality is:
So when 
then:
1. 24 students and 3 absent
24-3=21
so 21 student goes
2. 21 students divided by the 3 vans
equals to 7
so 7 student went in each van

Answer:
x+9
Step-by-step explanation:
f(x) = x, going up 9
that is y=x, going up 9
if you wnat to go up, subtract 9 from y
y -9 = x
y=x+9
convert back to f(x)
f(x) = x+9
Use the exponential function of f(x)= 100x times (1.08)^2
