Answer:

Answer:

#2 Karen is 7 years old

#3 Amy will be 31 years old in 10 years

Step-by-step explanation:

2#:

b+3=2(k+3)
b-2=3(k-2)
2b+1=5k
2b-5k=-1
b-2k=3
2b-4k=6
2b-4k-(2b-5k)=6-(-1)
k=7

3#:

a+1=2(s-5)
a+s+8=45
a-2s=-11
a=37-s
37-3s=-11
-3s=-48
s=16
a=37-16
a=21
21+10=31

Try finding what the amount for 1 t-shirt would be: 23 divided by 4. We get 5.75. What we can do next is multiply 5.75 by 2 since we're trying to find out the cost of 6 t-shirts, this gives us 11.5. So now we add 23 to 11.5. We get 34.5. This means that 6 t-shirts would cost $34.50
