    Answer: a) 13 macaroons

    b) 6 cookies

    Step-by-step explanation: Total = $10

    a) $2.20/slice of pie

    $0.60/macaroon

    10 - 2.20 = 7.80

    7.80/0.6 = 13

    b) $4.60/loaf

    cookies = 1 1/2*macaroons = (1 + 0.5) * 0.6 = 1,5 * 0.6 = 0.90

    cookies = $0.90

    10 - 4.60 = 5.40

    5.40/0.9 = 6
