You can solve the following proportion by cross multiplying. What will the equation be after you cross multiply? 3 x= 9 • 15
3 x = 15
3 • 15 = 9 X
15 = 9 X

=====================================

Explanation:

Anything in the form A/B = C/D will cross multiply to A*D = B*C

In this case, A = 3, B = 9, C = x and D = 15

So that's why 3/9 = x/15 cross multiplies to 3*15 = 9*x

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
