Sheila bought a new computer for $2000 and has agreed to finance it at 12% interest, with $100 payments each month. When she mak
es her first payment next month, how much will she pay for interest alone?
1 answer:
Answer:
rate per month = .01 agreed = r
Luckily they only ask for the first month so it is 0.01 * 20 .
Later months get more complicated and it is like paying off a mortgage with the term unknown but the rate and payment known.
Payment = principal value [ r / {1-(1+r)^-n } ]
100 = 2000 [ .01 / {1 - (1.01)^-n } ]
5 = 1/ {1 - (1.01)^-n }
.2 = 1 - (1.01)^-n
.8 = 1.01^-n
log .8 = -n log 1.01
n = 22.4 months :)
so over the almost two years pay 2240 total :)

Step-by-step explanation:
The sine of an angle is equal to the cosine of its complement, so
ANSWER: width (w) = 11 ft
w = 3L + 5
P = 2w + 2L = 26
P = 2(3L + 5) + 2L = 26
P = 6L + 10 + 2L = 26
P = 8L + 10 = 26
Now solve for L
8L = 16
L = 2
Now plug in 2 for L in the W equation
w = 3L + 5
w = 3(2) + 5
w = 6 + 5
w = 11
Width is 11 ft
Length is 2 ft

Answer:
20 and 10
These are the only two possible numbers who match those descriptions.
The answer would be -8.
collect like terms. (3x - 3x) + 2 - 10.
