Question

Nikki makes $9.50 an hour working at Current Electronics. She plans to buy a DVD recorder that costs $269.60. Write and solve an inequality describing how many hours h Nikki will have to work to be able to buy the DVD recorder.

Answer 1

Well let's break it down
$9.50 is what she makes an hour. Her goal is to earn $269.60
Step 1: First we need to write a variable. Our variable can be h since it is how many hours she need she to work
Step 2: Think! She works 9.50 and hour so our hour variable can go right aftear the nine! (Lots of people make the mistake of 9.50xh but sometimes the x can be confusing especially since x is the most common used mathematical variable, so always out it right next to it or use a dot in the middle)
Step 3: Piece it all together. So she makes 9.50h. And her goal is $269.60, so all we have to do now is $9.50h=$269.60. Since the equal sign makes this an accurate inequality.
NOW WE HAVE TO SOLVE IT
Since we are using multiplication in our inequality you can use the reverse operation of division to solve 9.50h= 269.60. Simply you just have to divide. 269.60/9.50.
