Ben wants to buy a new car stereo and he has already saved some money. he used this inequality to represent the amount he still has to save to be able to buy the stereo, where a represents the amount still left to save. if ben saves $15 a week for the next 10 weeks, will he be able to buy the stereo and why?

If Ben saves $15 a week for the next 10 weeks, he can save as much as $150. If the stereo cost less than the sum of what Ben saved already and the $150, then he can surely buy the stereo. However, if the amount that Ben needs to save which is represented by "a" is greater than $150, then he will not be able to buy the car stereo.

Basic algebra equation. first set up your equation: divide out 9.and now you are left with 2x + 4 = 8.
