Karen and Tom sold candy bars for a fundraiser, Karen sold 7 less than twice the number of candy bars that Tom sold. In total, Karen and Tom sold 137 candy bars. Find the amount of candy bars
sold by each

Create two formulas and use substitution.

K = 2c -7 (89)
T = c (48)
Substitute

K + T = 137

2c-7 + C = 137 (Group)
3c-7 = 137 (Add 7 to both sides)
3c = 144 (divide by 3)
C = 48 (Substitute to each individual)

2(48) -7 = 89

B. 16is the absolute value
