Answer:
1.99
Step-by-step explanation:
The Length would be 3
5+5= 10
16-10 =6 / 2 =3
When y=2 and y=5
1. 2y-1 and (3y-5+y or 4y-5)
when y=2 ; 2(2)-1 = 3 and 4(2)-5=3
when y=5 ; 2(5)-1 = 9 and 4(5)-5=15
----nonequivalent-----
2.5y+4 and (7y+4-2y or 5y+4)
so you don't have to place any value in because 5y+4 and 7y+4-2y are equal,
whatever you place any value in, it will be all the same then
-----equivalent------
and no need to find more
32*1.2=38.4 (.2 is the 20%, and the 1 adds the percent to the original cost making it a mark up)
