PLEASE HELP EXTRA POINTS 100 Cingular's plan charged $39.99 per month with $0.45 for each additional minute. Verizon's plan cost $44.99 with $0.40 for each additional minute. How many additional minutes, A, would it take for the two plans to cost the same?

44.99-39.99=5.00

5.00÷.45=11.11 additional minutes i would round to 11 because you can't have a fraction of an additional minute.

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
