Answer:

x = \frac{4\pi }{3}

Step-by-step explanation:

given

cos(x - \frac{\pi }{3}) = - 1, then

x - \frac{\pi }{3} = cos^{-1}(- 1) = π

Add \frac{\pi }{3} to both sides, hence

x = π + \frac{\pi }{3} = \frac{4\pi }{3}

Francis paid $36.54 for a computer software program after a fifteen percent discount was applied to the original selling price.
tigry1 [53]

Answer:

$42.02

Step-by-step explanation:

15% discount therefore if you want to find the original price it would be 100% plus 15% = 115%

Multiply the percentage (convert to decimal first) with the discounted value:

1.15(36.54) = 42.021
