Explain whether each situation represents a direct variation or an inverse variation. (please and thank you)
A) The cost of a $50 birthday gift is split among some friends
B) You purchase some peaches at $ 1.29/lb
+23254 A direct variation is one in which as one variable increases so does the other.
An inverse vairation is one in which as one variable increases, the other decreases.
In the first problem, the more friends are involved, the less each one has to pay -- inverse.
In the second problem, the more peaches you buy, the more you have to pay -- direct.
