If pounds was x
a. 0.65x is the equation.
2 pounds would cost $1.30
b. 0.65x-0.05x is the equation.
So exponenetial growth or decay
it goes like this
f(t)=P(1+r)^t
r=rate of decay or grouth
if r>0 then it is grouth by r
if r<0 then it is decay
i
P=initial amount
so
given
f(x)=5500(1.65)^t
f(x)=5500(1+0.65)^t
0.65>0 so it is growing by 65%
Graphed V hope his helped
Y is less than or equal to 16 because the graph never goes higher than 16
Answer:
a
Step-by-step explanation:
that shows
0+4.5=4.5-2.5=2
