If you are going to use mental math, round $0.98 up to $1.
Rounded, the cost of the 30 songs is $30.
However, since you rounded at the beginning, you need to subtract 2 cents for every song you purchased from the total of $30.
Multiply 30 by $0.02 to get $0.60. Subtract $0.60 from $30.
Your answer should be $29.40.
Answer:
$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
