    The cost per ounce is $1.99

    Step-by-step explanation:

    We can find the cost per ounce by using proportion.

    Let x be the cost of one ounce

    5 ounce = $9.95

    1 ounce = x

    Cross-multiply

    5x = $9.95

    Divide both-side of the equation by 5

    5x/5 = $9.95/5

    At the left-hand side of the equation 5 will cancel-out 5 leaving us with x

    x = $1.99

    The cost per ounce is $1.99
