Answer:
Andy ate 41 hot dogs
Barry ate 36 hot dogs
Carl ate 26 hot dogs
Step-by-step explanation:
Let the quantity of hot dogs eaten by Andy, Barry and Carl be A, B and C respectively.
Andy ate 5 more than Barry =>
A = B + 5. (Equation i)
Carl ate 10 less than Barry =>
C = B - 10. (Equation ii)
The three atr the total or 103 hot dogs.
ie. A + B + C = 103 (Equation iii)
From i and ii, substitute (B + 5) for A and (B - 10) for C in equation (iii)
(B + 5) + B + (B - 10) = 103
B + 5 + B + B - 10 = 103
B + B + B + 5 - 10 = 103
3B - 5 = 103
3B = 103 + 5
3B = 108
B = 108/3
B= 36
From equation (i)
A = B + 5
A = 36 + 5
A = 41
From equation (ii)
C = B - 10
C = 36 - 10
C = 26
Andy ate 41 hot dogs
Barry ate 36 hot dogs
Carl ate 26 hot dogs
