* Read about Cowling’s Rule for child sized doses of medication (number 92 on page 119 of Elementary and Intermediate Algebra). * Solve parts (a) and (b) of the problem using the following details indicated for the first letter of your last name: Explain what the variables in the formula represent and show all steps in the computations. * Incorporate the following five math vocabulary words into your discussion. Use bold font to emphasize the words in your writing (Do not write definitions for the words; use them appropriately in sentences describing your math work.): * Literal equation * Formula * Solve * Substitute * Conditional equation Cowling's rule is another function for determining the child's dosage of a drug. For this rule, the formula below expresses the child’s dosage d as a function of the adult dosage D and child’s age as a. d=D(a+1)/24 (Cowling Rule Formula) To show my understanding of this discussion my last name starts with S so I am going to use the formula above. I am going to substitute 500mg for D and for a I am going to substitute 4 for the age of the child, and so the formula should look like this d=500(4+1)/24 d=500(5)/24 (Following the order of operation you can see that I solved the parenthesis first.) d=2500/24 (Next in the order of operation was multiplying the above numbers.) d= 104mg (The final step was dividing in the order of operation and this would be the dosage for the child after solving the expression.) As instructed for this discussion I will show the age of the child based upon the dose of medicine he was prescribed. We can use the same literal equation, however we are solving for a different variable. This time we are using 300 for the adult and 100 for the child a. d=D(a+1)/24 (Cowlings rule formula) 100=300(a+1)/24 (I substituted 100 for d and 300 for
