Know a are:
CW=75. SL= 250. Y= 2x
CW= X= number of wings
SL= Y= number of sliders
X+Y= Total number of items, which can be rewritten as X+2X= total
Plug in the calories for the total
2(75X) +250X= 800
150x+250X= 400X= 800
X= 800/400=2 pieces of Slider
Double the amount for Wings=2x2=4
4wings/2 Sliders
4x-6= x+6
4x= x + 12
5x= 12
X= 12/5
X= 2.5
Answer:
C
Step-by-step explanation:
A =
r²
so we do
5² = 25 * 
25 * 
= 78.5 square units
I think you need to figure out how much he makes an hour first then its very easy from there.
