Answer:

Nicholas bought 1.8 lbs, and Jane bought 3lbs.

Step-by-step explanation:

Divide the total amount by how much it is per pound, so 8.10 divided by 4.50 = 1.8 and 9.75 divided by 3.25= 3

Answer:

Nicholas has purchased 1.8 pounds of pixie sticks.

Jane has purchased 3.0 pounds of Jolly ranchers.

Step-by-step explanation:

Cost of 1 pounds of pixie sticks = $4.50

Let the number of pixie sticks = x

Total  money spend on x pounds of pixie sticks = $8.10

\$4.50\times x=\$8.10

x=\frac{\$8.10}{\$4.50}=1.8 pounds

Nicholas has purchased 1.8 pounds of pixie sticks.

Cost of 1 pounds of Jolly ranchers = $3.25

Let the number of Jolly ranchers = y

Total  money spend on y pounds of Jolly ranchers = $9.75

\$3.25\times y=\$9.75

x=\frac{\$9.75}{\$3.25}=3.0 pounds

Jane has purchased 3.0 pounds of Jolly ranchers.

10x+4y+ 12z=120 <br> 11x +77y =220 <br> 8x +2y +32z =160
Damm [24]

Answer:

x=8.94 ; y = 1.58; z=2.02

Step-by-step explanation:

solve 10x+4y+12z = 120      →          5x+2y+6z = 60

         8x + 2y +32Z = 160   →           4x+y+16z = 80

To eliminate z multiply first equation by 16 and second equation by 6.

80x+32y+96z = 960

24x+6y+96z =   480

on subtractionwe get 56x+26y = 480

dividing by 2 we get, 28x + 13y = 240

Now we have a given equation 11x + 77y = 220 → x + 7y = 20

solving 28x + 13y = 240 and x + 7y = 20

28x + 13y =240

28x + 216y = 560

subtracting we get, 203y = 320

y = 1.58

x = 8.94

z = 2.02

You have just arranged for a $1,560,000 mortgage to finance the purchase of a large tract of land. the mortgage has an apr of 5.
seraphim [82]
P=1560000
APR=5.6%
monthly interest, i=5.6%/12=7/1500  [fractions keep exact values]
R=1+i=1+7/1500
# of periods, n=30 years = 360 periods
monthly payment, A
A=PR^n(i)/(R^n-1)
=1560000*(1+7/1500)^360*(7/1500)/((1+7/1500)^360-1)
=$8955.632

At the end of eight years,
number of periods, n1 = 8*12 = 96

If paid off at the end of 8 years, value of loan then
future value of principal
F1=PR^n1=1560000*(1+7/1500)^96=2439135.635
future value of payments
F2=A(R^n1-1)/i=8955.632*(1+7/1500)^96-1)/(7/1500)=1081485.620
Therefore the balloon payment
= future value of principal (owing) - future value of payments (paid)
=F1-F2
=2439135.635-1081485.620
=1357650.0152
Round to two places after decimal to get final answer.
