A prepaid phone card has a balance of $22.40 remaining. If calls are $0.035 per minute, which equation represents the number of minutes, m, you may talk using the card?

The equation that represents the number of minutes that Imay talk using the card is .

Step-by-step explanation:

From statement we know that balance (), measured in US dollars, is directly proportional to remaining call time (), measured in minutes. That is:

(Eq. 1)

Where is the proportionality ratio, measured in US dollars per minute.

If we know that , then the equation is:

Now we clear remaining call time within equation:

The equation that represents the number of minutes that Imay talk using the card is .

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
