Jennifer is leasing a car from a local auto retailer. The terms of the lease include a 9% interest rate for 36 months with a res

Allushta [10]

Answer:

d. $312.06

Step-by-step explanation:

The terms of the lease include a 9% interest rate for 36 months with a residual value of 57%

So, residual value is = $17500\times0.57$ = $9,975

The value of the car = $17500-9975$ = $7,525

Monthly payment = $\frac{7525}{36}$ = $209.03

Interest incurred = (17500+9975)\times0.00375= $103.03

Hence, Jennifer’s monthly lease payment will be =

$209.03+103.03$ = $312.06

Jessica bought 3/4 lb of berries. Mary bought 1/6 lb of berries less the jessica. what is the total weight of berries in pounds

Mrrafil [7]

Given that number of pounds of berries that Jessica bought = $\frac{3}{4}$ lb

Given that "Mary bought $\frac{1}{6}$ lb of berries less the jessica"

then number of pounds of berries that Mary bought

$=(\frac{3}{4}-\frac{1}{6})$ lb

$=\frac{3}{4}\cdot\frac{3}{3}-\frac{1}{6}\cdot\frac{2}{2}$ lb

$=\frac{9}{12}-\frac{2}{12}$ lb

$=\frac{7}{12}$ lb

Now we need to find the total weight of berries in pounds that they bought.

To find that we just need to add both values.

$\frac{3}{4}+\frac{7}{12}$

$=\frac{3}{4}\cdot\frac{3}{3}+\frac{7}{12}$

$=\frac{9}{12}+\frac{7}{12}$

$=\frac{16}{12}$

$=\frac{4}{3}$

Hence final answer is $\frac{4}{3}$ lb.

Phil has 50 nickels and dimes worth $4.15. How many dimes does he have

Katen [24]

Answer: Phil has 33 dimes, and 17 nickels

Step-by-step explanation:

Let number of nickels be X, and dimes be Y.

X + Y = 50.

Since nickels stand for 5 cents, or 0.05 dollars, and dimes are 10 cents, or 0.10 dollars, we can also write the total worth as:

0.05*X + 0.10*Y = 4.15

Multiply this last equation by 20:

20*0.05*X + 20*0.10*Y = 20*4.15

Simplify:

X + 2*Y = 83

Subtract the first equation (X + Y = 50) from this one:

Y = 33.

Thus Phil has 33 dimes, and 17 nickels.
