Answer:
$1.5
Step-by-step explanation:
So you need to subtract 25 from 13 = 12 then take 3 and 5 and add = 8 then you need to divide 12 from 8 = 1.5 so i do believe that the tubes are $1.5
I may be wrong and im sorry but pls try :3
Turn 1 7/8 into 15/8
15/8 times 4/5 is60/40
60/40 is 1.5
I think they all will make it a function.
