Did you figure it out?

Answer:  17/9 pounds

Solution:  After Soren takes a 40° slice, there are 320° of pie left. That’s 320 ÷ 360 = 8/9 of the pie, and 8/9 of 2 pounds is 17/9 pounds of pie.

 

 

 

 

 

 

 

 

 

 

Did you figure it out?

Answer:  $8.00

Solution:  If the average of all 4 pies is the same as the price of the peach pie, then the average of the first 3 pies must be equal to the price of the peach pie. To find the average price of the pies, we add the prices of the first 3 pies together, then divide by 3. 

$6.00 + $11.00 + $7.00 = $24.00

$24.00 ÷ 3 = $8.00
