Answer:
y=8/(p+q+4)
Step-by-step explanation:
py+qy=-4y+8
Collect all terms containing y together
Py+qy+4y=8
Factor out y
y(p+q+4)=8
Divide both sides by (p+q+4)
y(p+q+4)/(p+q+4)=8/(p+q+4)
y=8/(p+q+4)
40 total spins
it landed on H 15 times which equals 15/40
15/40 reduces to 3/8
the answer is C 3/8
Answer:
$4.257
Step-by-step explanation:
Given:
Items delivered per hour = 14
Fixed hourly costs = $47
variable cost = $0.90
Now,
at breakeven point, the profit = 0
or
Total revenue = total cost
let the charge at breakeven point be 'x'
thus,
x × 14 = $47 + ($0.90 × 14)
or
x × 14 = $47 + $12.6
14x = $59.6
or
x = $4.257
Hence, the breakeven charges are $4.257
