Answer:
cost = $10
Step-by-step explanation:
let cost be x
Price = x+ (0.5x)= 1.50x
cost reduced in term of x is 20% of 1.50x
* 1.50x = 0.3x
hence 1.50x - 0.3x = 12
1.2x=12
x=
= 10
cost = $10
.26*24= $6.24/ day :) hope this helps
If y=f(x)
Domains are input or plug in value of x which we put in equation for a variable accordingly we get output or y's values which is called range.
