Answer:
the original price is $80
Step-by-step explanation:
25% off would be 1/4 of the original price, leaving the rest of the 75% as the discounted price. So if $60 is 1/3 of the price then divide 60 by 3 which equals $20. $20 would be the 25% discount taken off and the original price would be $80.
Answer:
B) 26%
Step-by-step explanation:
The yellow part of the graph represents Rock, which is 15%, and the red part of the graph represents Classical. So, you simply add them together.
Current population = 500,000
Populaton is
500,000 * (1.0375) after 1 year
500,000 * (1.0375)² after 2 years
...
500,000 * (1.0375)ˣ after x years
Therefore when the population reaches a million,
500,000 * (1.0375)ˣ = 1,000,000
1.0375ˣ = 2
x ln(1.0375) = ln(2)
x = ln(2) / ln(1.0375) = 18.83 years
Answer: 18.8 years, or approximately 19 years.
Answer:
3.6
Step-by-step explanation:
-8(4+9x)=7(-2-11x)
-32-72x=-14-77x
-32+5x=-14
5x=18
x=3.6
