Question

Elena is trying to figure out how many movies she can download to her hard drive. The hard drive holds 500 gigabytes of data, but 58 gigabytes are already taken up by other files. Each movie is 8 gigabytes. How many movies can Elena download? Use the inequality 8​x​ + 58 ≤ 500, where ​x​ represents the number of movies she can download, to solve. Explain your solution.

8x+58<500

-58 -58 Subtract 58 on both sides

8x<442

/8 /8 Divide by 8 on both sides

X<55.25
