Topic: **How to write an algebraic expression****Question:**
Chris spent $9.06 for each DVD and $7.13 for each CD. He purchased three more CDs than DVDs, and the total amount of money spent was less than $119.47. Let x represent the number of DVDs he purchased, and write an algebraic expression for each item in parts a through d.
a) The total cost in dollars of the DVDs
b) The number of CDs
c) The total cost in dollars of the CDs
d) The sum of the costs is less than $119.47
e) Solve the inequality in part d (round to the nearest whole number)
does anyone know how to set up an equation for this

I think it'd be something like- x*9.06 + (x+3)*7.13 < 119.47 for a) you would get x*9.06 for b) you would get x+3 for c) you would get (x+3)*7.13 for d) you would get what I've written above You can do e

a.) 119.47-9.06(x) b.)x+3 c.)118.53-9.06(x) d.)s<119.47 (assume s=sum of cost) e.)119<119.47 Basically he bought 9CD's and 6 DVD's equaling the total cost of 118.53 or 9(7.13)+6(9.06)=118.53<119.47 hope this helps.

Oh goody math :) may want to check my answer befor it is your final answer (X*9.06)+(x+3)(7.13)<119.47

Just curious, here. Have you any idea why this type of problem is given in your school studies? It's to teach you to think and reason! When a student cheats on these questions, as you are now, it only hurts themselves., therefore I don't think that anyone should be doing other peoples homework on here! I know I know, it makes you feel as if you are the most intelligent person on the face of the earth to be able to answer questions like this one, but you really need to let this person do it for themselves, otherwise they will be nothing but a cheat and a liar all their lives!
