Answer:
Step-by-step explanation:
3.45/5=0.69
0.69x$125=86.25
0.75x$125=93.75
93.75-86.25=$7.5
Troy would get $7.50 more than he would have if the exchange rate had stayed at .69
A, divide 2.5 by 5 and you get 0.5, multiply that by 9 and you get 4.5. A is the answer
Try using fraction, i think the ans is 28/205 ;)
