    Answer: 110 test were purchased

    Step-by-step explanation:

    Set P = number of packets of 10 test

    Total cost = $30 + $11 x P = $151

    $11xP = $151 - $30 = $121

    P = $121/$11 = 11 packets were purchased

    Test purchased = 11packets x 10 test/packet = 110 test were purchased

    Answer: 110 test were purchased
