    @Halia Can you please check the problem. Is the wording exactly correct? Being off by just a small word can change a lot.

    A book means a book of stamps, and we are told each book of stamps has 20 stamps.

    but I understand the envelopes part 2 x 1.89 = 3.78 total for envelopes... yeah I knew I got that term confused.

    Stamps: 3 * 20 * $0.19 = $11.40 Envelopes: 2 * $1.89 = $3.78 Total = $11.40 + $3.78

    1 book of stamps ->20 2 book of stamps ->40 3 book of stamps ->60 60 stamps @ 19 cents a piece => 60 x .19 = $11.40 $1.89 x 2 = $3.78 $11.40+$3.78 = ? calculate the total using addition
