Respuesta :
8f + 3r > 8r + 3f
8f + 135> 360 + 3f
125 : 5 = 25
each folder was .70
8f + 135> 360 + 3f
125 : 5 = 25
each folder was .70
Each folder price was 0.70 if Sarah bought 8 folders and 3 rulers. Lea bought 8 rulers and 3 folders. Sarah paid $1.25 more than Lea.
What is inequality?
It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
It is given that:
Sarah bought 8 folders and 3 rulers. Lea bought 8 rulers and 3 folders.
Sarah paid $1.25 more than Lea.
Let f be the cost of each folder
Let r be the cost of each ruler
From the data given we can frame linear inequality as follows:
8f + 3r > 8r + 3f
8f + 135> 360 + 3f
125 : 5 = 25
Each folder was $0.70
Thus, each folder price was 0.70 if Sarah bought 8 folders and 3 rulers. Lea bought 8 rulers and 3 folders. Sarah paid $1.25 more than Lea.
