Since you need to find the area of a square napkin, you need to know what the formula for a square is. It is height multiplied by base. So a square is equal in all sides. 8×8=64
Answer: 64 in²
To determine the percent change in price, solve for the differences between the original prices and the sale prices. Then, divide the difference by the original price and multiply by 100%.
Guitar 1: (($160 - $100) / $160) x 100% = 37.5%
Guitar 2: (($250 - $150) / $250) x 100% = 40%
Thus, guitar 2 has a greater percent change in price.
Answer:
34.4

Answer:
Retail Price = $155
Step-by-step explanation:
The retail price is 55% MORE than the manufacturer buying price.
The manufacturer buying price is $100. So the retail price would be 55% MORE.
Firstly,
55% in decimal is:
55/100 = 0.55
Now 55% of 100 is:
0.55 * 100 = $55
So, the retail price is $55 MORE, so the retail price is:
100 + 55 = $155
Retail Price = $155
2x-3y=13...(1)
2x+4y=-8...(2)
Multiply equation 2 by -1 to eliminate x
2x-3y=13
+ -2x-4y=8
—————
-7y=21
y=-3
Substitute y=-3 into equation 2
2x+4(-3)=-8
x=2
Therefore, the solution to the system is (2, -3)
