Edna decided to purchase a $15,000 MSRP vehicle at a 5% interest rate for 3 years. The dealership offered her a $1500 cash-back
Ad libitum [116K]
P = A/D, Where P = Monthly payments, A = Total amount owed = 15,000-1,500 = $13,500,

D= \frac{( 1+ \frac{r}{12} )^{nt} -1}{ \frac{r}{12} (1+  \frac{r}{12}) ^{nt} }

r = 5% = 0.05, nt = 12*3 = 36

Therefore,
D = \frac{(1+ 0.05/12)^{36}-1 }{(0.05/12)(1+0.05/12)^{36} } = 33.37

Then,

P = 13,500/44.37 = $404.61
The correct answer is c.

Bess has $2.80 in quarters and dimes. The number of dimes is 7 less than the number of quarters. Find the number of quarters and
Nezavi [6.7K]

Answer:

3 dimes and 10 quarters

Step-by-step explanation:

If you add 7 dimes, then the number of dimes and quarters is the same, and the total increases to $3.50. A dime and a quarter have a value together of $0.35. Since there are equal numbers, the value $3.50 must be made up of some quantity of groups with a value of $0.35. That number of groups must be ...

... $3.50/$0.35 = 10

Thus, there are 10 quarters and 10-7 = 3 dimes.

_____

<em>Using an equation</em>

Let q represent the number of quarters. Then the amount Bess has is ...

... 0.10(q -7) +0.25q = 2.80

... 0.35q - 0.70 = 2.80

... 0.35q = 3.50 . . . . . add 0.70 . . . . . . . this should look familiar

... q = 3.50/0.35 = 10
