Question

Tammy buys a 4-gigabyte memory card for her camera. Dijonea buys a memory card with twice as much storage as Tammy’s. One gigabyte is 1,024 megabytes. How many megabytes of storage does Dijonea have on her memory card?

Answer 1

Dijonea have 8192 megabytes on her memory card

Explanation:

Capacity of Tammy's memory card = 4-gigabyte

given that Dijonea buys a memory card with twice as much storage as Tammy’s

Thus,

Capacity of Dijonea's memory card = 2*Capacity of Tammy's memory card

Capacity of Dijonea's memory card = 2*4-gigabyte = 8-gigabyte

Given that

1 gigabyte = 1,024 megabytes

we have to find value of 8 gigabyte in terms of megabytes

for that we multiple both side in above equation by 8

1 *8 gigabyte = 1,024 *8 megabytes

8 gigabyte = 8192 megabytes

Thus, Dijonea have 8192 megabytes on her memory card
