Let Sam be (S+8) years while his sister is S years.
S(S+8) = 105
S^2+8S-105 = 0
(S+15)(S-7) = 0
Sam’s sister is 7 years and Sam is 15 years old.

I'm not sure if you meant the tax was on the original proce or not, so here's both answers:
Tax on original price: $3010
Tax after sale: $2968
To get the amount off from the sale
3500x.2=700
3500-700=2800
To get the tax
(Tax on original price) 3500x.06=210
(Tax after sale) 2800x.06=168
Add tax onto price
(Tax on original price) 2800+210=3010
(Tax after sale) 2800+168=2968
Answer:
5456 sq. inches
Step-by-step explanation:
Let width = w,
Then length = w + 26
Perimeter = 2[length + width]
2[(w +26) + w] = 2[2w + 26] = 4w + 52
Perimeter given is 300
So, 4w + 52 = 300
4w = 248
w = 248/4 =62
length = 62 + 26 = 88
Area = length × width
Area = 88 × 62 = 5456 sq. inches
