Answer: 5 gigabytes
Step-by-step explanation:
Her budget is $60 and since she already spends a starting price of $38.5 you would use this equation:
60-38.5=21.5
Since you are left with $21.5 and it’s $5 per gigabyte you will use this equation:
21.5 /5= 4.3
This means she can get 4.3 gigabytes which is rounded to 5 while staying within her budget.
