Bailey has a video streaming service with a flat monthly fee of $18.00 plus an additional cost of $3.50 for each premium movie r
ental. Bailey can only afford a maximum monthly bill of $40.00. Which inequality can be used to solve for x, the number of premium movie rentals she can purchase in a month?
She pays 18 dollars each moth, therefore that quantity won't change, so you will have to add. Each movie that she watches is an additional 3.50, then we have 3.50 x, x being the quantity of movies that she watches. She can only afford up to 40 dollars, then everything that she spends has to be less or equal to 40.
1) subtract 2y in both sides: (7y-2y)-6=(2y-2y)+8 which is 5y-6=8 2) Add 6 to both sides: 5y(-6+6)=8+6 which is 5y=14 3) Divide 5 on both sides: 5y/5=14/5 which is y=14/5 or y=2.8 or y=2 4/5
