You buy 30 of your favorite songs from a web site that charges $0.98 for each song. what is the cost of 30 songs? use mental math.

$29.40

Step-by-step explanation:

When we use mental math to calculate, we simplify the values to calculate them easily.

Since a website that charges $0.98 for each songs rounded to $1.00

You buy 30 of your favorite songs = 30 × 1

                                                          = $30.00

Now subtract 2 cents × 30 = 60 cents or $0.60

$30.00 - 0.60

= $29.40

The cost of 30 songs is $29.40
