Eighty percent of the students in a class (group A) share 40% of the candy equally. The remaining 20% of the students (group B)

mestny [16]

Answer:

1/6

Step-by-step explanation:

There is x candy in total and y students in total.

Group A consists of 0.8y students, and group B consists of 0.2y students.

Group A gets 40% of x, or 0.4x. Each student in group A gets 0.4x/(0.8y) = 0.5x/y candy per person.

Group B gets 60% of x, or 0.6x. Each student in group B gets 0.6x/(0.2y) = 3x/y candy per person.

The ratio of candy each student in group A has to the amount of candy each student in group B has is:

(0.5x/y)/(3x/y) = 0.5/3 = 1/6

Sharon will borrow $3400 at 11% APR. She will pay it back over 18 months. What will her monthly payment be?

omeli [17]

The first step to calculate the APR is to calculate the interest rate per $100

Here Interest rate = 11%

Term or time of repayment = 18 months

interest per $100 =

$100 × 11% × $\frac{18}{12}$

= $16.50

Now we should calculate the interest part for $3400 for 18 months

$\frac{3400}{100}$ × $\frac{16.50}{18}$

= $31.12

So $ 31.17 is the interest part of the repayment amount

Now lets calculate the principal part which would be $ 3400 divided equally for 18 months

$\frac{3400}{18} = $188.89$

Now to find the final payment we add the interest and the principal part

$31.17+$188.89 = $220.06

Hence option D is the right answer
