Answer:
Step-by-step explanation:
let one charge=x
second charge=135-x
20x+(135-x)5=1800
4 x+135-x=360
3x=360-135=225
x=75 $
first charges $ 75 for 20 hours
second charges =135-75=$60 for 5 hours.
a= 7
b=9
c=4
Answer: $1.28 = cost of 8 oranges
$1.60 / 10 = cost of 1 orange
$0.16 = cost of 1 orange
$0.16 (8) = cost of 8 oranges
$1.28 = cost of 8 oranges
The correct answer is C. not skewed
