Jaime is preparing for a bicycle race . His goal is to bicycle an average of at least 280 miles per week for 4 weeks. He bicycled 240 miles the first week, 310 miles the second week , and 320 miles the third week.. Which inequality can be used to represent the number of miles,x Jaime could bicycle on the 4th week to meet his goal? (240+310+320)/(3)+xgeqslant 280 B) 240+310+320geqslant x(280) C) (240)/(4)+(310)/(4)+(320)/(4)+xgeqslant 280 D) 240+310+320+xgeqslant 4(280) A B C D

To find the correct inequality, we need to calculate the total miles Jaime needs to bike in 4 weeks to meet his goal of an average of at least 280 miles per week.First, let's calculate the total miles Jaime has biked in the first 3 weeks: Next, let's calculate the total miles Jaime needs to bike in 4 weeks to meet his goal: Now, let's set up the inequality to find the number of miles, , Jaime needs to bike in the 4th week: Simplifying this inequality, we get: So, the correct inequality is: Now, let's compare this inequality with the given options:A) B) \(240+310+320\geqslant x(280)\)C) D) \(240+310+320+x\geqslant 4(280)\)Option D is the correct one: So, the correct answer is D.
