Answer:
$23.56
Step-by-step explanation:
Step one:
given data
We are told that the unit cost per pound is $5.89
Required
the cost of 4 pounds
If 1 pound cost $5.89
4 pounds cost x
cross multiply
x= 4*5.89
x=$23.56
1. y= 3x -10
2. y= -5x + 7
3. y= x -9
4. y= 2/3x- 6
5 y= -x + 2 1/2
x<-2
12x>6x+12-15 (first distribute)
12x>6x-3 (simplify)
6x>-3 (put like terms on one side by subtraction)
x<-2 (divide and switch inequality sign since you divided by a negative)
