MAIL Serena went to the post office to mail some party invitations. She had $6.15. If each invitation needed a $0.41 stamp, how many invitations could she mail?
Words Total is equal to cost of each stamp times number of invitations mailed.
Variable Let n represent the number of invitations mailed.
Equation 6.15 = 0.41n
