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)
