Anthony has an average (

) of 11.33 (to the nearest

hundredth).
On the calculator,

represents the total sum of the weights.

= 1 + 0.5 + 1 + 0.5.

x represents the weighted sum of his scores.

(12)(1) + (13)(0.5) + (10)(1) + (11)(0.5) = 34.
Change Anthony’s last score from 11 to 15.

If the teacher adds 4 points to Test 4, Anthony’s average

grade is 12.
