Gina is comparing four long distance phone plans. the table shows the cost of each plan. if gina plans to use less than 500 minutes each month, the most cost effective plan is plan a plan b plan c plan d

I am also answering that same question on a website for algebra and have the same question and i think the answer is A.

Plan A

Step-by-step explanation:

Gina plans to use less than 500 minutes each month.

The cost four plans are given in the table.

Let's find the cost of each plan assuming that Gina use 500 minutes.

Plan cost = Monthly fee + const per minute

Plan A cost = $15 + 500*0.05 = $15 + $25 = $40

Plan B cost = $5 + 500*0.15 = $5 + $75 = $80

Plan C cost = $10 + 500*0.10 = $10 + $50 = $60

Plan D cost = $20 + 500*0.20 = $20 + $100 = $120

By comparing the price, the Plan A is cost effective plan.

therefore, the answer is  Plan A.

it could 14.28 but if its not that one then it has to be the 17 one. hope this ! : )
