Question

Tamika makes $ 378.00 on the sale of a home theater system that costs $9.000.00. Express her rate of commission as a percent rounded to the nearest whole number

Answer 1

4%

Explanation:

commission rate = (amount earned on sales / total cost of items sold) x 100

`(378)/(9000)` × 100 = 4.2%

To convert to the nearest whole number, look at the first number after the decimal,

1. if it is equal to or greater than 5, add 1 to the number before the decimal
2. if it is less than five, add 0 to the number before the decimal

two is less than 5, thus we would add zero to 4.

4.2% becomes 4%
