If it was priced at $100 and had 30% off, it would cost
($100 - (30% of $100)) =$70.
If there was an additional 20% off, it would cost
($100 - (30% of $100) - (20% of 30% of $100)) = $56.
So the total savings is (100-56)/100=44%.
For $74.99, the answer is the same but the numbers are slightly different,
(74.99 - (30% of 74.99) - (20% of 30% of 74.99))/74.99 = 44%.
3 cm X 4 cm X 5 cm is the answer
Answer:
6 bushes and 2 fences
Step-by-step explanation:
Let 2x be the no. of bushes and 2y be the no. of fences
2x+2y = 8
18(2x)+25(2y) less than/equal to 164
2y = 8 - 2x
18(2x) + 25(8-2x) 《 164
36x + 200 - 50x 《 164
14x 》 36
x 》 18/7
x = 3
y = 1
2x = 6
2y = 2
