The expression is 8 x 5 + -26.
She now has 14 dollars.
We know that she paid 8 * 5 = $40, and we know that she got $26 back, so her net total of money she has is 40 - 26 = $14.
The percentage of students who spend less than 4 hours a week on screens which reported a grade average below 80 is 50%
Given, we have the report representing children spending time online, on social media or watching T.V, which has there effect on there grades as above or below 80.
By the question we know that the number of students who spends less than 4 hours a week on screen is:
9 + 9
= 18
And among the 18 students there are 9 students whose grade average is below 80.
So the percentage of the students who spends 4 hours a week on screen is:
