You can  put this solution on YOUR website! P+I=1,050 
P=150+2I 
(150+2I)+I=1,050 
3I=1,050-150 
3I=900 
I=-900/3 
I=300 CALORIES FOR THE ICECREAM. 
P=150+2*300 
P=150+600 
P=750 CALORIES FOR THE PIE. 
PROOF: 
750+300=1,050 
1,050=1,050

------------------ 
Equations: 
p + c = 1050 calories 
p = 2c + 150 
----------- 
Substitute for "p" and solve for "c": 
2c+150 + c = 1050 
3c = 900 
c = 300 (# of calories in the ice cream) 
------------------- 
p = 2c + 150 
p = 600 + 150 
pie = 750 (# of calories in the pie)
