A coupon subtracts $5.16 from the price (p) of a shirt. You pay $15.48 for the shirt after using the coupon. Write and solve an

lbvjy [14]

The equation would look like: p - 5.16 = 15.48

because the coupon subtracts 5.16 from p and the price you pay is 15.48

Solve the equation by adding 5.16 to both sides

p = 20.64

The original price of the shirt is $20.64

You can use the formula P=A(i/1-(1+i)-n) monthly payment on a loan of A dollars that is paid back in equal monthly payments over

Dafna11 [192]

Answer:

$48.54

Explanation:

We must express the interest rate on a monthly basis.

i = 8 %/yr = 0.6667 %/mo = 0.006 667

A = $4000

n = 120 mo

$P = A(\frac{i}{1-(1+i)^{-n}})$

$P = 4000(\frac{0.006667 }{1-(1+0.006667)^{-120}})$

$P = \frac{26.67}{1-0.006667^{-120}}$

$P = \frac{26.67}{1-0.4505}$

$P = \frac{26.67}{0.5495}$

P = 48.531

The banks round up the numbers, so Seki’s monthly payment is $48.54.
