a cell phone company has a basic monthly plan of $40plus $0.45 for many minutes ised over 700. John was charged a total of $48.1
jonny [76]
Cost of month plan = $40

Cost of minutes used = $0.45 after 700 minutes

Total cost = $48.10

Let x be the total minutes used
Total cost = 40 + 0.45(x - 700)

------------------------------------------------------------------
Form the equation and solve x
------------------------------------------------------------------
40 + 0.45(x - 700) = 48.10
40 + 0.45x - 315 = 48.10
0.45x - 275 = 48.10
0.45x = 48.10 + 275
0.45x = 323.10
x = 323.10 ÷ 0.45
x = 718

------------------------------------------------------------------
Answer: John had used 718 mins this month

How do you make 22 percent into fraction in simplest form
exis [7]

22% in fraction form is 22/100 or 0.22, but it isn't the simplest form.

To put 22/100 into a simplest form, you must divide the numerator <em>and </em>the denominator by a common multiple.

22/100 or 0.22 is divisible by 2. Therefore, you can divide 22/100 by 2.

Equation:

22/100 divided by 2/2 =  11/50

Hence your answer, 11/50

Hope this helps!
