Answer:
The processing fee will cost $8.76
Step-by-step explanation:
the price after the discount:
20% = 0.2
100% = 1
1 - 0.2 = 0.8
0.8
$73 • 0.8 = $58.4
cost of processing fee:
15% = 0.15
$58.4 • 0.15 = $8.76
Since both 2 and 5 are prime numbers, there are no multiples for the fraction 2/5.
4⁽²ˣ ⁺ ⁵⁾ = 8³ˣ
But 4 = 2² and 8 = 2³
4⁽²ˣ ⁺ ⁵⁾ = 8³ˣ
2²⁽²ˣ ⁺ ⁵⁾ = (2³)³ˣ
Multiply out the powers, also since the
2⁴ˣ ⁺ ¹⁰ = 2⁹ˣ
Since the bases are the same, hence the powers are also the same.
4x + 10 = 9x
4x - 9x = -10
-5x = -10
x = -10/-5
x = 2
Hope this explains it.
