Answer:
The balance amount owed on the credit card altogether = $258.43
Step-by-step explanation:
Here, the current amount owed on the credit card = $225.45
Now, the amount of payment made to the credit card = $55.00
So, the remaining amount owed = Current Debt - Paid Amount
= $225.45 - 55 = $170. 45
Again, the purchase amount at Macy's = $87.98
⇒ New amount owed on credit card = Previous Debt + New Purchase
= $170. 45 + $87.98 = $258.43
Hence, the balance amount owed on the credit card = $258.43
Percent increase = (new number - original number) / original number...* 100
= (39.99 - 29.62) / 29.62....* 100
= 10.37 / 29.62....* 100
= 0.35 * 100
= 35% markup <===
Answer: x = { 2 ; 3 }
+) x² - 3 = x² - 1 - 2 = (x - 1)(x + 1) - 2
+) x² - 3 is divisible by x-1 but (x -1)(x + 1) is divisible by x-1
=> 2 must be divisible by x-1
=> x - 1 is divisor of 2
=> (x - 1) ∈ {-1; 1; 2; - 2;}
but x > 1 => x - 1 > 0
⇒ x - 1 = {1; 2; }
+) with x - 1 = 1 => x = 2
x - 1 = 2 => x = 3
