Question

Nancy needs at least 1000 gigabytes of storage to take pictures and videos on her upcoming vacation. She checks and finds that she has 105 GB 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 GB and cost $10. She wants to spend as little money as possible and still get the storage she needs. Let C represent the number of memory cards that Nancy buys. 1) Which inequality describes this scenario? Choose 1 answer: 105 + 100 < 1000 105 + 100 > 1000 105 + 2560 < 1000 105 + 256C 1000

Answer 1

The total GB is 1000

The available GB is 105 GB.

Each 256 GB and cost $10.

Let C be the number of memory cards, then we have,

`105+256C\ge1000`

Thus, option D is correct.
