    Therefore Josiah must sell 68 or 69 or 70 tacos in order to meet the requirement.

    Step-by-step explanation:

    Given, Josiah owns a food truck that sells tacos and burritos.

    He sells each burritos for $7.50. If 79 burritos were sold.

    Then the price of 79 burritos is $ (7.50*79) = $592.50

    Let x tacos were sold.

    He sells each tacos for $5.

    Then the price of x tacos is = $ (x * 5) = $5x

    Also given that Josiah must sell a minimum of $930 worth of tacos and burritos.

    Therefore,

    5x+592.50≥ 930

    ⇔5x≥930-592.50

    ⇔5x≥337.5

    ⇔x≥67.5

    But he only has enough supplies to make 149 tacos or burrito.

    He already sold 79 burrito.

    So, remain space for tacos is = (149-79) = 70

    So, 67.5≤x≤70

    ∴x = 68 or 69 or 70

    Therefore Josiah must sell 68 or 69 or 70 tacos in order to meet the requirement.
