as infants grow from a toddler to a young adult, there may be times when they are ill and medication is needed. it is extremely important that medication be administered in the exact dose so the child receives the correct amount. too little or too much medication could have serious side effects. a popular children’s fever medicine manufacturer recommends the following dosage information to parents and pediatricians.

A) Rate of change is 0.208
Rate of change is change in Y divided by the change in X. Let Y be the Dosage. Let X be the Weight.
Subtract first dosage from the second:
7.5 - 5 =2.5

Subtract the first weight from the second:
36 - 24 = 12

Now divide:
2.5 ÷ 12 = 0.208

b) It is linear. Instead of subtracting the first from the second, just subtract the second from third:
10 - 7.5 = 2.5
48 - 36 = 12

Or the third from the fourth
12.5 - 10 = 2.5
60 - 48 = 12

Or the fourth from the fifth
15 - 12-5 = 2.5
72 - 60 = 12

What do you notice? You get 2.5 and 12 for all of them, thus the relationship is linear.

Really any number between them works. for example 144.951
