which will be:
-0.01=a
25% markup = original + 25% = 125% of original = 1.25 x original
Selling price = 1.25 x dealer price
Answer = 521.25/1.25=$417
Linear pairs add up to 180 degrees.
7w - 20 + w + 100 = 180
8w + 80 = 180
8w = 100
w = 12.5
BNR = 7w - 20 = 87.5 - 20 = 67.5
RNA = w + 100 = 112.5
RNA is bigger by 112.5 - 67.5 = 45.
w = 12.5, BNR = 67.5, RNA = 112.5,
RNA is bigger by 45 degrees.
You need to mow 8 lawns because 15 times 7 equals 105 and thats over 92
Answer:
