Commision equals percentage times the amount of money bought for the car. It will be 1.5% (0.015) * 22500. The answer is $337.50.
The slant height of a square pyramid with those specifications would be 6.7 units.
Write the equations,
10 c + 5 f = 6900
5c + 3f = 3660
Double,
10c + 6f = 7320
Subtract,
f = 7320 - 6900 = 420
10 c = 6900 - 5f = 6900 - 2100 = 4800
c = 480
Answer: Cheeseburger 480 calories, fries 420 calories
Check:
10 (480) + 5 (420) = 4800 + 2100 = 6900 good
5(480) + 3(420) = 2400 + 1260 = 3660 good
