Answer:
Step-by-step explanation:
Let b represent the number of black
ink pens that John wants to buy.
Let r represent the number of red
ink pens that John wants to buy.
John wishes to buy 20 pens. This would be expressed as
b + r = 20
The store sells black ink pens for $5 and red ink pens for $4. John doesn’t wish to spend more than $92. The inequality to show this information would be expressed as
5b + 4r ≤ 92
