A. If you use only the coupon you will have to pay $137.50.
B. Using the Coupon during the sale, the kit is discounted by $112.50
C. The total percent discount is 45% after both discounts.
Step-by-step explanation:
Step 1; The store has the robotics kit for a sale of 25% off $250. So we need to find how much 25% is in terms of $250. To do that we convert 25% into a fraction by dividing it by 100 and multiplying it with $250.
25% of $250 = 
× $250 = 0.25 × $250 = $62.50
So we find the cost of the kit due to the store's discount. To do that we subtract the discounted price from the original price.
Robotics kit price after 25% discount = $250 - $62.50 = $187.50.
Step 2; A coupon you have gives you an additional 20% discount. So the robotics kit can be brought for 25% off due to the sale at the store, due to this coupon you get an additional 20%. So you get a 45% discount off $250.
45% of $250 = 
× $250 = 0.45 × $250 = $112.50.
So to find the total discount we subtract this $112.50 from the non-discounted cost of $250.
Total discounted price = $250 - $112.50 = $137.50.

The solutions of the equation 
² - 16 = 0is 4/3 and -4/3 and that of the equation 
is 8 and -4.
Solving the both quadratic equations by extracting square roots:
⇒ 
∴ On taking square-root of both sides, we get
= 
⇒ 
and 
⇒ 
= 4/3 and = -4/3
For the equation, , the solution is:
⇒ 
∴ On taking square-root of both sides, we get
⇒ (z - 2) = 6 and (z - 2) = -6
⇒ z = 6 +2 and z = -6 + 2
⇒ z = 8 and z = -4
The solution of the equation is 4/3 and -4/3.
The solution of the equation is 8 and -4.

D Robby got a credit of -245.75 for returning the guitar but purchased the new one for +368.45=+122.70 that Robby still owes for the bass guitar.
Well, one year is 365 days, and a leap year is every 4 years with an extra day, making leap years 366 days. 2016 is the nearest leap year. So, We take 365 from 1001 to get 636 days. Now it is January 1st 2016. So, subtract 366 from 636 to get 270 days. It is now January 1st 2017. There are 31 days in December, 30 in November, and 31 in October. Adding these together, you get 92. Subtracting 92 from 365, we get 273. So three days before October 1st is when you end. There are 30 days in September, so taking three away gives us the night of the 27th of September, 2017. So, the date you finish, if staying on a schedule of reading a bit each night, would be the night of September 27th, 2017, which is a Wednesday.
