Total amount of shirt and sneakers: $61.18
Amount leftover: $38.82
This equation can be solved graphically by plotting the equations
f(x) = 3^x
and
g(x) = 5x-1.
The x-coordinate of the point(s) of intersection is the solution.
_____
On my graphing calculator, I find it easier to locate x-intercepts, so I would rewrite the equation as
3^x -(5x -1) = 0
and plot the function
h(x) = 3^x -(5x -1)
The x-intercept(s) would be the solutions. (There are two: x≈0.577, x=2.)
Answer:
Factoring
Step-by-step explanation:
(x+4)² = 15
x² + 8x + 16 = 15
x² + 8x + 1 = 0

I hope this helps you :)
Emily gave Jake 20% of the buttons. 20% = 15 buttons, and 15 x 5 = 75
