She must have a score greater than 69 in her final tests

Let the required score be "x"

The mean of the data is the ratio of the sum to the total sample

Mean = 80+76+85+85+x/5

80+76+85+85+2x/5 > 79

326+x/5 > 79

326 + x > 395

x > 395 - 326

x > 69

This shows that she must have a score greater than 69 in her final tests
