Maria’s hard drive holds 1.0 ×10^6 megabytes of data. Larry has two hard drives, one that holds 5.1 × 10^5 megabytes of data and one that holds 7.7 × 10^5 Which statement is true? A) Maria can store more data than Larry because 10^6 > 10^5 B) Larry can store more data than Maria because 5.1 + 7.7 = 12.8 and 12.8 > 1.0 C) Larry can store more data than Maria because the sum of his hard drive space is 1.28 ×10^5 D) Larry can store more data than Maria because the sum of his hard drive space is 1.28 ×10^6

Given:

Maria’s hard drive stores 1.0 × 10^6 megabytes of data.

Larry has two hard drives,

Hard drive A = 5.1 × 10^5 megabytes of data

Hard drive B = 7.7 × 10^5

Hard drive A = 5.1 × 10^5

Hard drive B = 7.7 × 10^5

Hard drive A + hard drive B

5.1 × 10^5 + 7.7 × 10^5

= 12.8 × 10^5

Making sure Maria's hard drive and Larry's hard drive are in the same standard form

= 1.28 × 10^6

Maria's hard drive can only store 1.0 × 10^6 megabytes of data while Larry's hard drive can store 1.28 × 10^6

Therefore,

D) Larry can store more data than Maria because the sum of his hard drive space is 1.28 × 10^6
