The inequality which can be used to determine the number of gigabytes is 45 + 3x < 60
The given parameters are
Flat cost = $45
Rate = $3 per gigabyte
Budget = Under 60
The equation is represented as:
Total cost = Flat cost + Rate * Number of gigabyte
So, we have
y = 45 + 3x
The budget is under 60
So, we have
45 + 3x < 60
Hence. the inequality which can be used to determine the number of gigabytes is 45 + 3x < 60
