Solve.

−43x+16<79

please solve

Answers

-43x + 16 < 79

Subtract 16 from both sides,
-43x < 63

Divide -43 from both sides,
x < -63/43

Hope this helps!

-43x + 16 -16< 79 -16; -43x ÷ -43 < 63 ÷ -43; x > -1.47

Step-by-step explanation:

Mike is looking for a loan. He is willing to pay no more than an effective rate of 8.000% annually. Which, if any, of the following loans meet Mike’s criteria?Loan X: 7.815% nominal rate, compounded semiannually
Loan Y: 7.724% nominal rate, compounded monthly
Loan Z: 7.698% nominal rate, compounded weekly
a. Y only
b. X and Z
c. Y and Z
d. None of these meet Mike’s criteria.

Answers

Answer:

b. X and Z

Step-by-step explanation:

Since, the effective annual rate is,

$i_a=(1+(r)/(m))^m-1$

Where r is the nominal rate per period,

m is the number of periods in a year,

For loan X,

r = 7.815 % = 0.07815

m = 2,

Thus, the effective annual rate,

$i_a=(1+(0.07815)/(2))^2-1$

$=(1+0.039075)^2-1$

$=1.07967685563-1=0.07967685563=7.967685563\% \approx 7.968\%$

Since, 7.968\% < 8.000 %

Thus, Loan X meets his criteria.

For loan Y,

r = 7.724%= 0.07724

m = 12,

Thus, the effective annual rate,

$i_a=(1+(0.07724)/(12))^(12)-1$

$=(1.00643666667)^(12)-1$

$=1.08003395186-1=0.08003395186=8.003395186\% \approx 8.003\%$

Since, 8.003 > 8.000 %

Thus, Loan Y does not meet his criteria.

For loan Z,

r = 7.698% = 0.07698

m = 52,

Thus, the effective annual rate,

$i_a=(1+(0.07698)/(52))^(52)-1$

$=(1.00148038462)^(52)-1$

$=1.07995899887-1=07995899887=7.995899887\% \approx 7.996\%$

Since, 7.996 % < 8.000 %

Thus, Loan Zmeets his criteria.

Hence, option 'b' is correct.
