2. A phone company charges a base fee of $12 per month plus an additional charge per minute. The monthly phone cost C can be represented by this equation: C = 12 +a. m, where a is the additional
charge per minute, and m is the number of minutes used.
Which equation can be used to find the # of minutes a customer used if we know and a and C?
A. m = (C-12)
B. m = (C - 12)-a
C. m = C - 12a
(C-12)
D. m =
a
E. m = 8-12

Given:

The  monthly phone cost C can be represented by this equation:

where, a is the additional  charge per minute, and m is the number of minutes used.

To find:

The equation can be used to find the number of minutes a customer used if we know and a and C.

Solution:

We have,

We need to isolate m on one side.

Subtract 12 from both sides.

Divide both sides by a.

The options are not in proper format.

Therefore, the required equation is .

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
