Kevin is choosing between two cell phone plans that offer the same amount of free minutes. AT&T’s plan charges $19.99 per month with additional minutes costing $0.35. Verizon’s plan costs $34.99 with additional minutes at $0.30. How many additional minutes, a, will it take for the two plans to cost the same? *

Step-by-step explanation:

Step one:

Given data

AT&T’s plan

monthly charge= $19.99

additional charge per minute= $0.35

let the number of minutes be x

let the total charges be

y=0.35x+19.991

Verizon’s plan

monthly charge= $34.99

additional charge per minute= $0.3

let the number of minutes be x

let the total charges be

y=0.3x+34.992

Step two:

equating the two equations above we have

0.35x+19.99=0.3x+34.99

collect like terms

0.35x-0.3x=34.99-19.99

0.05x=15

divide both sides by 0.05

x=15/0.05

x=300

For the two plans to cost the same, it will take 300 minutes

step-by-step explanation:

du what else would it be

brainliest

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides
