Answer:
B. 3/5
Step-by-step explanation
1/5 of icing = 1/3 of a cake
1/3 * 3/1 = 3/3 = 1 (a whole cake)
1/5 * 3/1 = 3/5
Couldn’t quite read everything, the writing is very light. But from what I could read, it was correct for the most part. :)
◆ Define the variables:
Let the calorie content of Candy A = a
and the calorie content of Candy B = b
◆ Form the equations:
One bar of candy A and two bars of candy B have 774 calories. Thus:
a + 2b = 774
Two bars of candy A and one bar of candy B contains 786 calories
2a + b = 786
◆ Solve the equations:
From first equation,
a + 2b = 774
=> a = 774 - 2b
Put a in second equation
2×(774-2b) + b = 786
=> 2×774 - 2×2b + b = 786
=> 1548 - 4b + b = 786
=> -3b = 786 - 1548
=> -3b = -762
=> b = -762/(-3) = 254 calorie
◆ Find caloric content:
Caloric content of candy B = 254 calorie
Caloric content of candy A = a = 774 - 2b = 774 - 2×254 = 774 - 508 = 266 calorie
First day = 10 +8
=18
second day = 8+8
=16
3rd=16
4th= 16
5th=16
6th=16
16+16+16+16+16+18
=80+18
=98
