145-60=85. That is the answer

300=br
280=dvd&br
But there's 320 ppl so 320-280=40
Whole package weighs 20pounds
1.65 = 5pounds
0.12 = extra pound
3.45 - 1.65 = 1.80 : 0.12 = 15pounds
Adding up 15pounds and the first 5 pounds equal 20 pounds
6 3/3 = x + 2/3
18/3 = x + 2/3
18/3 - 2/3 = x
16/3 = x
5 1/3 = x
