Myra wants to save at least $500 by the end of her summer vacation. she currently has $350 saved. she can earn $25 cutting a lawn in her neighborhood. myra solves an inequality to determine the least number of lawns, n, she must cut to reach her goal.?

Since this is an inequality we need more than just the equal sign, but it can help to create a linear equation to get it.  we only need to define one variable since they give us one, so what i will use is M=total money earned 

M=350+25N

now simply replace your equation sign with the less than or equal to sign ()  and the M with the 500 since Myra wants at least that.

500350+25N

now we must look for the least amount of times Myra needs to mow lawns, use the linear equation because exactly $500 is earned. this will be our M

500=350+25N

now take away 350 from each side so we can get N alone

150=25N

now divide each side to get N completely alone and that will give us the least amount of lawns Myra will need to mow to get to her goal

6=N, and since this was supposed to be an inequality replace the equal sign with the less than or equal to sign, 6N, or at least 6 lawns need to be mowed to get to Myra's goal
