A long-distance phone call between two cities costs $4.42 for 17 minutes. What is the rate in cents per minute?

Novosadov [1.4K]

Answer:

The rate is $r = \frac{442}{17} = 26$

Step-by-step explanation:

The rate, in cents per minute, is given by the multiplication of the how much you paid by 100 and divided by the number of minutes.

The multiplication by 100 happens because the cost is in dollars, and each dollar has 100 cents. So

$r = \frac{100*4.42}{17} = \frac{442}{17} = 26$
