Question

Choose or write the equation that models the situation. Do NOT solve.Write an equation to model the final cost of the book C. The final cost is p, theoriginal price of the book, minus a 25% of the original book price. Combine liketerms.C = 0.75pC = p - 25C=P - 25O p = 0.250

Answer 1

Given that the cost is C

And the original price p. The cost C is the original price of the book less 25% of p

This may be interpreted mathematically as

C = p - 25% *p

= p - 0.25p

= 0.75p

Hence C = 0.75p
