Question

Under his cell phone plan, Angel pays a flat cost of $35 per month and $5 per gigabyte. He wants to keep his bill under $50 per month. Write and solve an inequality which can be used to determine x, the number of gigabytes Angel can use while staying within his budget.​

Answer 1

4 gigabytes

Explanation:

$55-$35 =$20

Under $55 = less than (<) $55

According to given question we have,

$35 + $5 × g < 55

35 + 5g < 55

compare like terms and simplify we get,

5g < 55 - 35

5g < 20

g < 20/5

g < 4 gigabytes

Answer 2

Inequality: 5x + 35 <50

Answer: x < 3
