Write an inequality:
When Susie bought her Yorkie puppy, she was promised he should weigh less than 6 pounds when he is full grown. Right now Mikey weighs 2.5 pounds. Write and solve an inequality to represent the amount of weight Mikey can gain and still be within the seller’s promised weight.
*
Let x represent the amount of weight Mikey can gain.
The inequality representing the seller's promised weight is:
2.5 + x < 6
Solving for x:
x < 6 - 2.5
x < 3.5
Therefore, Mikey can gain up to 3.5 pounds and still be within the seller's promised weight.
