Question

Bill bought a new cellular phone. His monthly bill will be $34.99 each month which includes 100 minutes of use. Additional minutes will cost $0.23 per minute. Write an equation that represents the cost of the bill C in terms of m, which is the number of minutes used ABOVE the 100 that are included in the base price. a. C = 34.99(m - 100) + 0.23 c. C = 0.23m b. C = 0.23m + 34.99 d. C = 0.23(m - 100) + 34.99

Answer 1

B) C=0.23m+34.99

because you get you base price definitely and extra minute price can be removed if you don't use more than 100

Answer 2

d. C = 0.23(m - 100) + 34.99

Explanation:

Let C = X + Y, where

C = Cost of the bill in terms of m

X = First term of the equation

Y = Second term of the equation

X = add additional minutes to $ 0.23 minus the 100 minutes of use allocated.

X = 0.23 (m - 100)

Y = Base price monthly will be $ 34.99

Y = 34.99

C = X + Y

C = 0.23 (m - 100) + 34.99

Note: The only possible answer is 0.23 (m - 100) + 34.99, but we must assume that "m" is greater than or equal to 100, that is, Bill consumes at least his 100 minutes assigned by the base price.

Hope this helps!
