Sandy went to the post office with $20. She mailed a package for $3.67. Write and solve an inequality to find the greatest amount of $.37 stamps Sandy could have purchased?

Step-by-step explanation:

Total money = $20

amount for mailing package = $ 3.67

Price for one stamp = $ 0.37

Let number of stamps be x,

Price for x stamps = $.037x

Price for x stamps + amount for package should not exceed $20

0.37x+3.67 ≤ 20

Solving for inequality,

x≤ 44.1

Since x should be whole number,

x ≤ 44
