Answer :
first round 15.25 to 15.30 and round 4.85 to 4.90 and then add you get 21.20 no it is not reasonable and you round to the decimal ones
Answer: It's not reasonable.
Step-by-step explanation:
Hi, to answer this question we have to add both book’s prices:
15.25 + 4.85 = $20.1
If he wants to pay with one $20 bill, it wouldn’t be reasonable, because:
20 <20.1
For an useful estimate, estimate to the nearest tenth:
15.30 +4.90 = 20.2
Still, he can’t afford the books because he is lacking 20 cents.
