Given:
Regular Price = 390.00
Discount on 4th tree = 80%
Sales tax : 8.25%
If bought at regular price:
4 * 390 = 1560
1560 * 8.25% = 128.70
1560 + 128.70 = 1688.70 total cost
If promotion is availed.
3 * 390 = 1170
1 * 390 * (1-.8) = 78
1170 + 78 = 1248
1248 * 8.25% = 102.96
1248 + 102.96 = 1,350.96 total cost
Total cost: w/o promotion and w/ promotion
1,688.70 - 1,350.96 = 337.74 SAVINGS IN USING THE PROMOTION
The answer is x= 5 or x= -5
Answer: approximately 10.8 centimeters
Step-by-step explanation:
We have a square, where each side measures approx. 4.25 in
Now we know that 1in ≈ 2.54 cm
Then, in 4.25 in, we have 4.25 times 1 inch, so we have 4.25 times the length of 2.54 cm
So the approximate measure of the sides in centimeters is:
4.25*(2.54)cm = 10.8 cm
So we have that each side measures approximately 10.8 centimeters
