a cell phone plan costs $28.90 per month for 400 minutes of talk time. it costs an additional $0.07 per minute for each minute over 400 minutes. to get e-mail access, it costs 10% of the price for 400 minutes of talk time. your bill, which includes e-mail, is the same each month for 8 months. the total cost for all months is $298.56. write and solve an equation to find the number of minutes of talk time you use each month.

Equation = 195.12=6(0.06m+23.70+0.20(23.70))

Minutes = 2541

Step-by-step explanation:

Okay so you take the equation (195.12 = .06m+23.7+ 0.8(23.7)))

Then you simplify to get 152.46 = 0.06m

And then m is equal to 2541 :)

I hope this helps !

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
