A travel agent earns 7% commission on every cruise booked. How much commission does a $3,900 cruise booking earn?
A$237
B$327
C$273
D$253
Answer & Solution
Correct answer: C. $273
1. The commission equals the rate of commission times the total sales.
2. Change 7% to a decimal: 0.07.
3. Multiply: 0.07 x 3,900 = 273.
4. So the commission is $273.
5. $237 and $327 are digit rearrangements of the right answer, traps for someone estimating instead of multiplying.
