Tricia has a birthday party. During the party, she opened 36 gifts, which was 60% of all her gifts. After the party, she opened the rest of the gifts and found that 25% of them were the same present, so she returned all but one of the duplicate gifts. How many gifts did she return?
1 answer:
Answer:
She returned 5 gifts.
Step-by-step explanation:
36 gifts is 60% = 0.6 of all the gifts that she received. How many presents are 100% = 1?
36 gifts - 0.6
x gifts - 1
0.6x = 36
x = 36/0.6
x = 60
She received 60 gifts.
She opened the rest of the gifts and found that 25% of them were the same present
The rest is 60 - 36 = 24 gifts.
25% is (1/4)*24 = 6 duplicate figts
She returned all but one of the duplicate gifts.
That is, she returned 6 - 1 = 5 gifts.

Answer:
26-4s=9s
26-(4s-9s)=0
26+5s=0
5s=-26
ans: s= -26/5
-3r+10=15r-8
-3r-15r=-8-10
-18r=-18
18r=18
ans: r=1
-9(t-2)=4(t-15)
-9t+18=4t-60
-9t-4t=-60-18
-13t=-78
13t=78
ans: t=26
