1) The applicable formula is
I = Prt
I = $30,000×0.095×(120/365)
I ≈ $936.99
2) The same formula applies.
I = $30,000×0.095×(85/365)
I ≈ $663.70
3a) The interest due on day 30 is
I = $30,000×0.095×(30/365) ≈ $234.25
so the new balance is $30,000 - $10,000 + $234.25 = 20,234.25
3b) The amount due on day 85 is
A = P(1 + rt) = $20,234.25·(1 + 0.095·((85-30)/365))
A = $20,523.90
Write and solve an equation of ratios:
900 students 45 teachers
------------------ = -----------------
x 110 teachers
Cross multiplying, we get (900)(110) / 45, or
so x = # of students in the high school = 2200 (answer)
Answer:
140 coins total
Step-by-step explanation:
Straightforward, this reads "7 is 5% of how many?". Algebraically, the word "is" means an equals sign, and the word "of" means you multiply. Of course, the 5% needs to be in decimal form. Taking the sentence above, algebraically it is: 7 = .05x. Divide by .05 on both sides to get x = 140
Answer:
the answer would be the equilibrium of 28.59295
