Xander's water bottle has 15.4 oz of water in it, and he is drinking 0.5 oz of water each second. Leon's water bottle has 5.4 oz of water in it, and he is adding 0.75 oz of water each second. Which inequality could be used to find the number of seconds it will take for Xander's water bottle to have a fewer number of ounces than Leon's water bottle?
5.4 + 0.75x < 15.4 - 0.5x
0.5x - 15.4 < 0.75x + 5.4
15.4 + 0.5x < 0.75x + 5.4
5.4 + 0.75x > 15.4 - 0.5x

Vera is currently using 16,000 MB of storage on her phone, and she is deleting 2.2 MB of music each minute. Keira is currently using 11,275 MB of storage on her phone, and she is adding 16.7 MB of music each minute. Which inequality could be used to find the number of minutes it will take for Vera to be using no more than the amount of storage that Keira is using?
11,275 + 16.7m ≤ 16,000 - 2.2m
16.7m + 11,275 > 16,000 - 2.2m
16,000 - 2.2m ≤ 11,275 + 16.7m
2.2m - 16,000 < 11,275 + 16.7m
