Lois needs at least 750 gigabytes of storage to take pictures and videos on her upcoming vacation. She checks and finds that she has 215 gigabytes available on her phone. She plans on buying additional memory cards to get the rest of the storage she needs. The cheapest memory cards she can find each hold 256 gigabytes
Let C represent the number of memory cards that Lois buys.
Which inequality describes this scenario?
A. 215C + 256 ≥ 750
B. 215 + 256C ≤ 750
C. 215 + 256C ≥ 750
D. 215C + 256 ≤ 750
