Answer:
Dijonea have 8192 megabytes on her memory card
Step-by-step 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
