WORD PROBLEM:
Tims tet grades in french were:
86,96,88,91
what score must Tim make on his next test to average 92?
a 89

c 97

2) the water level indicator measures the rise and fall in meters of the water level in a resevoir. The o on the gauge indicates the normal water level in the reservoir. The water level at the end of the summer was
-2 and at the end of winter it was 1.

Find the difference between the 2 levels.
-2 - 1 = -3

-3 is the difference between the 2 levels.
is that right?
