Answer:
2.2 gigabytes
Step-by-step explanation:
Let us represent
x = the number of gigabytes of data Samuel can use while staying within his budget
Therefore, our equation is:
$41.50 + $5 × x = $52.50
41.50 + 5x = 52.50
Subtract 41.50 from both sides
41.50 - 41.50 + 5x = 52.50 - 41.50
5x = 11
x = 11/5
x = 2.2 gigabytes.
The number of gigabytes of data he need to keep his monthly cost at $52.50 is 2.2 gigabytes
