Question

At Noise Pollution Cellular, plan A is $30.00 per month and $5.00 for every gigabyte of data. Plan B is $50.00 per month and $2.00 for every gigabyte of data used. Irfan wants to find out which plan is the best choice for him. On average, he uses five to eight GB of data per month. How much data would Irfan need to use for both plans to cost the same (round 3 decimal places)?

Answer 1

lets use x for the gb used per month and lets say he used 8 gb per month. for plan a, the expression would be 30+5h. that equals to 70. Now plan b's expression is 50+2h. that would be 66. so in the end, plan b is still lower than plan a
