If Tyrone talks for 800 minutes each month and uses 1000 text messages, which plan is least expensive for him?  

Plan A  

Plan B  

Plan C  

Plan D

Step-by-step explanation:

The cheapest plan for Tyrone is the D: because it has unlimited free messages, and 500 minutes of free conversation, as 800 speaks, minus 500, there are 300 for which you would have to pay, 10 cent per minute, which would be $ 30 , plus the $ 45 that the plan costs, they would make a total of $ 75.

800 - 500 = 300 x 0.10 = 30 + 45 = 75 $

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1
