Answer:
$40.40
Step-by-step explanation:
1. Round each decimal to the nearest tenth. Keep in mind that the sum is the answer to an addition problem.
$4.28 = $4.30
$21.35 = $21.40
$14.65 = $14.70
2. Now, all we have to do is add up the three decimals to find the answer.
$21.40 + $14.70 + $4.30 = $40.40
Conclusion: Your answer is $40.40
