I think it’s 7 sorry if it’s wrong but I think it’s 7
Answer:
either 76 or 19
Step-by-step explanation:
76 if it's 1/5 of the original amount as well as 3/4 the original amount
1/5+3/4=19/20
3.80=1/20x
3.80+19/20x=76
3.8*20=76
19 if it's 1/5 of the original amount and 3/4 of the new amount
3.80=1/4y
3.80+3/4y=15.20
15.20=4/5x
15.20+1/5x=19
I think 725 would be the correct answer
