Solve the equation of the function for n.
a(n) = 3n - 20
a = 3n - 20
a + 20 = 3n
(a + 20)/3 = n
n = (a + 20)/3
n(a) = (a + 20)/3
33.3% is the answer, I think
20/60 ---> 1/3, covert this to a percentage and it equals 33.3%
Tony will get $8.26 back.
Here's why:
First, let's take $1.85 away from $13.59, because he has a coupon. That leaves us with $11.74
Second, do $20 - $11.74 to get your answer, $8.26
Answer:
36 in
Step-by-step explanation:
T= toucan
M= macaw
T= 2/3M
T= 24
24= 2/3M
72=2M
36= M
If y=mx+b,

You can't differentiate a constant, so dy/dx=m.
