Answer:
b= 3a-c
Step-by-step explanation:
Solve for b.
a= 1/3(b+c)
multiplying both sides by 3.
3a= b+c
subtract c from both sides.
3a-c=b
or
b= 3a-c
46 because 8-3 equals 5 then 5 times 5 equals 25 to then add 11 to finally subtract 66-20 which equals 46
B because the amount of money they earn per hour multiplied by how many hours they worked is equal to what they earned in total
