4) The Girls’ Scouts are sponsoring a cookie sale. If their goal is to raise at least $500.00, how
many cookies must they sell at $5.50 each in order to meet that goal? Write and solve an
inequality.
Let x be the number of cookies to be sold.
The inequality to meet the goal is:
5.50x ≥ 500
Divide both sides of the inequality by 5.50 to isolate the variable:
x ≥ 90.91
Since the number of cookies must be a whole number, the Girls' Scouts must sell at least 91 cookies to meet their goal.
