81.79 is approximately 80.
10% of 80 is 8
20% of 80 is 16
15% is right in between 10% and 20%, so the tip should be $12 which right in between $8 and $16.

1) The bakers at Healthy Bakery can make 290 bagels in 10 hours. How many
Ivenika [448]

Answer:

667 bagels in 23 hours

29 bagels per hour

Step-by-step explanation:

We first find the unit rate in bagels per hour.

(290 bagels) / (10 hours) = 29 bagels/hour

Now we find the number of bagels made in 23 hours.

23 hours * 29 bagels/hour = 667 bagels
