Answer:
Step-by-step explanation:
let wind velocity=x
speed of plane=y
(x+y)*4=808
x+y=808/4=202 ...(1)
(y-x)*4=488
y-x=122 ...(2)
add (1) and (2)
2y=202+122=324
y=324/2=162
from (1)
x+162=202
x=202-162=40
wind velocity=40 m/hr
speed of plane=162 m/hr
436 hamburgers and cheeseburgers sold Wednesday.
64 fewer cheeseburgers.
436/2= 218
218-64= 154
154 cheeseburgers were sold Wednesday.
They are going up by 2.15
He would need to sell 28 because
12.50*28=350 and 350+50=400
