Topic: How to write an algebraic expression
June 20, 2019 / By Hector
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
