Algebra:
a(3b-1)=2b+2
Solve for b

b =

Step-by-step explanation:

We have an algebraic expression and are asked to solve for b.

a(3b - 1) = 2b + 2

To solve we need to isolate b :

Distribute :

(a(3b) - a(1)) = 2b + 2

3ab - a = 2b + 2

2b + 2 = 3ab - a

Subtract 2 from both sides :

2b = 3ab - a - 2

Divide 2 from both sides :

b =

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
