Question

A mobile phone holds 1.28 x 10^11 bytes of storage. You can also pay more money to get an additional 384,000,000,000 bytes. How much storage would your phone have if you buy the additional bytes? The answer should be in scientific notation. (1 point)
• 385.28 x 10^11
• 385,280,000,000
• 512 × 10^9
• 5.12 x 10^11

Answer 1

The additional bytes that can be purchased are 384,000,000,000 bytes.
Adding this to the original storage capacity of 1.28 x 10^11 bytes gives a total of 1.28 x 10^11 + 384,000,000,000 = 385,280,000,000 bytes.
Therefore, the correct answer is 385.28 x 10^11.
