OLEGan [10]

Answer:

\$3886.8

Step-by-step explanation:

Commission received on selling each storm window =8\% of the selling price of each storm window

Commission received on selling each door =12\% of the selling price of each door

Amount earned on selling storm windows = $5,400

Amount earned on selling doors = $28,790

Commission received on selling storm windows =\frac{8}{100}(5,400)=\$432

Commission received on selling doors =\frac{12}{100}(28,790)=\$3454.8

Therefore,

Total  commission received =432+3454.8=\$3886.8

A question on my test:
Andre45 [30]

Answer:

180degrees

Step-by-step explanation:

Given the expression cos^2x - cos x - 2 = 0

Let P = cos x

P^2 - P - 2 = 0

Factorize

P^2 - 2P + P - 2 =0

P(P-2)+1(P-2) = 0

P-2 = 0 and P + 1 = 0

P = 2 and P = -1

Since P = cos x

cos x = -1

x = arccos(-1)

x = 180degrees

Hence the require angle is 180degrees
