Add up all the money for college and the note books ect then you have your answer
Hi there!
I believe the answer is $300.
Why?
Because 20 (bird houses) x 15 (money for each one) = $300
I hope this helps.
:)

STEPS FOR SOLVING LINEAR EQUATION
3y=4x+1
Swap sides so that all variable terms are on the left hand side.
4x+1=3y
Subtract 1 from both sides.
4x=3y−1
Divide both sides by 4.
4
4x
=
4
3y−1
Dividing by 4 undoes the multiplication by 4.
x=

3y−1
Answer:
f(9.5) = 558.02.
Step-by-step explanation:
Because it is an exponential function, it can be written: y = (a)(b)^x
Now substitute in the two known points:
72 = (a)(b)^7.5 and
2 = (a)(b)^4 : => since 2 = (a)(b)^2 divide the left side by 2 and the right by (a)(b)^2
72/2 =[(a)(b)^7.5]/[(a)(b)^4]: => the (a) cancels out and b becomes b^(7.5–4)
36 = b^3.5: => To isolate b take the 3.5 root of both sides
{3.5 root}(36) = {3.5 root}(b^3.5)
2.783927 = b
Now to solve for a
2 = (a)(b)^4 => 2 = (a)(2.783927)^4 => 2 = (a)(60.066375) divide both sides by 60.066375 0.0332965 = a
Equation: y = (0.0332965)(2.783927)^x
Now plug in 9.5 for x
(0.0332965)(2.783927)^9.5 = 558.0178525 = 558.02
Interval <-1;1>, which means that this function can take values from interval <-7;-1>. The minimum value is -7.
