Question

Andrea baked h muffins.Violet baked 8 fewer muffins than Andrea.Find the average number of muffins baked by both girls,in terms of h.

Answer 1

The number of muffins Andrea baked: h
The number of muffins Violet baked: h-8

In order to find the average, we add the two expressions and divide them by 2.
(h)+(h-8)=2h-8
(2h-8)/2=h-4

The average number of muffins baked is h-4 muffins.
