A cell phone plan costs $28.80 per month for 500 minutes of talk time. It costs an additional $0.06 per minute for each minute over 500 minutes. To get e-mail access, it costs %30 of the price for 500 minutes of talk time. Your bill, which includes e-mail, is the same each month for 7 months. The total cost for all 7 months is $288.54. Write and solve an equation to find the number of minutes of talk time you use each month. Let m represent the number of minutes over 500 minutes each month. Which equation represents the given situation?

A.288.54=7(0.06m+28.80+0.30(28.80))
B. 288.54=7(m+28.80+0.70(28.80))
C. 288.54=7(0.06m+28.80)

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
