Under his cell phone plan, Anthony pays a flat cost of $56 per month and $4 per gigabyte. He wants to keep his bill under $70 per month. Write and solve an inequality which can be used to determine xx, the number of gigabytes Anthony can use while staying within his budget.

x ≤ 3.5 gigabytes

Step-by-step explanation:

Under his cell phone plan, Anthony pays a flat cost of $56 per month and $4 per gigabyte. He wants to keep his bill under $70 per month.

Let us represent the number of gigabytes = x

Hence, our Equation is:

$56 + $4 × x ≤ $70

56 + 4x ≤ 70

Collect like terms

4x ≤ 70 - 56

4x ≤ 14

x ≤ 14/4

x ≤ 3.5 gigabytes

Therefore, the number of gigabytes Anthony can use while staying within his budget is less than or equal to 3.5 gigabytes

is the anwser b. (-13)?
