The student concluded that the number of resistors in parallel was inversely proportional to the mean total resistance.
Explain why the student was correct.
Use data from Figure 12 in your answer.

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form

not too sure thinking all accelerations are pointed down
