Answer:
82
Step-by-step explanation:

She spent:
(5x2)+150+40= 200$
200$----> 100%
40$-----> x
With x the percentage of the total sale she spent on shoes:
X= (40x100)/200
= 4000/200
=20%
If n=250, then 50% of n can also be described as n divided by 2.
50% of n = 250/2 = 125
answer: 125
Answer:
Average ROC = 0
Step-by-step explanation:
Average ROC : (f(b) - f(a)) / (b - a) ... slope = (y'-y) / (x'-x)
a = -3 f(a) = 10 ... x=-3, y=10
b = 6 f(b) = 10 ... x'=6, y'=10
Average ROC = (10 - 10) / (6 - -3) = 0 / 9 = 0
