Answer: $36.3
Step-by-step explanation:
Since Christopher bought 3 toy trucks that costs $14.25 each. Then, the cost of the three toys will be:
= 3 × $14.25
= $42.75
Then, if he used a coupon for 15% off of the total purchase, then the final purchase will be:
= $42.75 - (15% × $42.75)
= $42.75 - (0.15 × $42.75)
= $42.75 - $6.4125
= $36.3375
= $36.3
