1. We are given:
The only a which squared gives you 64 is 8. The perimeter of an 8 by 8 square will be 32. Half of that is 16. Now, let's see what we can do. We can set up:
Obviously, each side length has to be 4. So, the area of this square will be 16 units².
2. Let n equal her son's age. So, her age right now will be (S = her age):
1 year ago it was:
We have 2 equations, let's substitute. We can rewrite this as:
Solve for n:
We know the value of n, which is her son's age. So, her son is 1/15 of a year old or about 24 days old.

Answer:
The amount which Jada paid after discount and tax is $ 51.64
Step-by-step explanation:
Given as :
The original price of snacks = $ 53
The price of snacks after applying 10% off coupon = 53 - 10% of 53
Or , The price of snacks after applying 10% off coupon = 53 ( )
or, The price of snacks after applying 10% off coupon = 53 × 0.9 = $ 47.7
Now the tax applied on the original amount = 8 % of $ 53
or, the tax applied on the original amount = × 53
or, , the tax applied on the original amount = =$ 4.24
So The total paid amount = $ 47.4 + $ 4.24 = $ 51.64
Hence The amount which Jada paid after discount and tax is $ 51.64 Answer
