12:15 does not belong, since that is a ratio of 4:5, whilst the others are all 3:4.
I believe it's 12 because 5*16=80. So, then you would subtract 4 from 16 and gat 12.
Total hours worked = 5 x 3 = 15 hours
Amount collected = 50 x 15 = $750
Amount paid to the paralegal = 30 x 15 = $450
Amount made by the firm = 750 - 450 = $300
Answer:
increase by 18
Step-by-step explanation:
put any number at c
f=32+1.8(5)
f=41
Then increase your number c by 10
f=32+1.8(15)
f=59
then figure out the difference
59-41=18
Answer:
a) $370
b) $305 is from interest; $3695 comes from deposits
Step-by-step explanation:
(a) The formula variables are not defined here, so choosing the appropriate formula is difficult. I worked through the "A =" formula because I'm used to seeing a formula in which A is the payment amount. Not so, here.
Here, P is the payment amount. Since you're asked to find the amount of payment, you want to choose and evaluate the "P=" formula. Payments and compounding are 2 times per year, so n=2, and the term is 5 years, so t=5. The interest rate, r, is 3.5%, or 0.035.
Then your formula evaluates to ...
... P = A((1 +r/n)^(nt) -1)/(r/n) = 4000·0.0175/(1.0175^(2·5) -1) ≈ 369.50
Part A wants the amount rounded up to the nearest dollar, so $370.
(b) 10 payments of $369.50 will total $3695.00. This is the amount from payments. The remainder, $4000 -3695 = $305 is from interest.
