    15 small bottles

    30 large bottles

    Step-by-step explanation:

    Let the number of small bottle sold=s

    Let the number of large bottle sold=l

    She sold all 45 of the hand sanitizer bottles, therefore:

    s+l=45

    The small bottle sells for $5.00

    The large sells for $12.00

    She collected a total of $435

    5s+12l=435

    We solve the two equations simultaneously to obtain s and l.

    From the first equation, s=45-l

    Substitute s=45-l into 5s+12l=435

    5 (45-l) + 12l=435

    225-5l+12l=435

    7l=435-225

    7l=210

    Divide both sides by 7

    l=30

    Recall: s=45-l

    Therefore, s=45-30=15

    Allanah sold 15 small bottles and 30 large bottles of hand sanitizer.
