Aleah enjoys swimming and skating with her friends. She has a budget where she spends no more than $80 a month for her activities. Swimming costs $5 each time and skating costs $4 each time.
a) define the variables
b) are there any restrictions on the variables?
c) write a linear inequality to represent this situation
d) graph this linear inequality
a) define the variables The variables are x and y ; x can represent the number of times Aleah goes swimming ; while y can represents the number of times Aleah goes skating.
b) are there any restrictions on the variables? The total sum of both activities must be equal or less than $80 a month
c) write a linear inequality to represent this situation Swimming costs $5 each time and skating costs $4 each time. No more than $80 a month.
5x + 4y < 80
You can graph linear inequality using these coordinates. x y 16 0 12 5 8 10 4 15 0 20
