Let
C-----------------
> charges for the purchases to the credit card
<span>r-------------------
> the interest rate </span>
X------------------
> total cost of the purchase
we know that
C=4120
r= 22.45%=0.2245
X=C*(1+r)
substituting the values in the formula
X=(4120)*(1+0.2245)=
(4120)*(1.2245)=5044.94
the answer is
$5044.94
Correct answer would be D. hope this helps :)
74 + 5x + (3x + 2) = 180 ** The sum of the 3 angles in a triangle is 180**
74 +5x + 3x + 2 = 180
76 + 8x = 180
8x = 180 - 76
8x = 104
X = 13
