Answer:
The credit card purchase price of the same item is $87.5
Step-by-step explanation:
Here, we are interested in calculating the credit-card purchase price of an item if we are given the cash price
Since there is a 4% discount on the cash; the percentage paid will be 100-4% = 96%
So what we are saying is that, it is 96% of the credit cash purchase that was paid as cash;
Let the credit card purchase be $x
96% of x = 84
96/100 * x = 84
96x = 100 * 84
x = 8400/96
x = 87.5
Thus, the credit card purchase price of the same item is $87.5
The total area is 2( 2.5*3 +3*1.5 + 2.5*1.5) =2( 7.5 + 4.5 + 3.75) =2*15.75 = 31.5 ;
Note that c is the hypotenuse of the blue triangle, and that the Pyth. Thm. states that (length of one leg)^2 + (length of the other leg)^2 = (hyp)^2.
Therefore, (hyp)^2 = c^2 = [2sqrt(x^2+3x)]^2 + 3^2, or
= 4(x^2+3x) + 9, or
= 4x^2 + 12x + 9 = (2x+3)^2
Taking the sqrt of both sides, c = plus or minus (2x+3). Eliminate -(2x+3) because the middle term of the square of this would be negative, in conflict with the given +12x.
c=2x+3 is the correct answer.
