50.25
you have to find the area of the pizza first.
to do that you take half of the diameter 16
to get the radius 8
once you have the radius you square it 8*8 = 64
you than multiply it by pie 3.14
and get 200.95 or if you round 201
if you rounded you would get 50.25 if you didn't
than you would get. 50.24

Step-by-step explanation:





Wall = A=
The two equations expressed in this scenario will be
y = 13x + 34
And
y = 30x
I like substitution, so let’s use that
Plug in y = 30x for y in the first equation
30x = 13x + 34
Subtract
17x = 34
x = 2
Plug in 2 for x in any equation
y = 30(2)
y = 60
It would be 2 hours and she would pay $60 dollars
