Rachel pays a flat rate of $5 per month plus $.10 per minute for her long distance phone plan

Let "x" be the total number of minutes

Therefore,

Total monthly Bill = 5 + 0.10x

She wants her total monthly bill to be less than $20

So we have to use "less than or equal to" symbol

Thus maximum number of minutes, Rachel can talk to stay within her budge is 150 minutes
