Jan gives Ted a loan at 4% effective to be repaid by 10 annual payments of 100, followed by 5 annual payments of 200. Just after
olya-2409 [2.1K]

Answer:

139 ( D )

Step-by-step explanation:

Interest rate on loan = 4% = 0.04

Number of payments = 15

First 10 payments = 100 each

last 5 payments = 200 each

Calculating the value of K

K = [ ( 100 / 0.04 * ( 1-1 / 1.04^10 ) + 200/0.04 * ( 1-1 / (1 +0.04)^5)*  1 /1.04^10)

*  1.1 - 100 / 0.04 * ( 1-1 / (1+0.04)^5 ) - 200/0.04 * (1-1 /1.04^5) * 1/1.04^10)*0.04 / ( 1-1 / 1.04^5) * (1 + 0.04)^5

= 138.6051 ≈ 139

Evaluate 3xy + b if x = -4 ,y = 2 , and b = 5
olga2289 [7]

Answer:

-19

Step-by-step explanation:

ok so since they give you all the variables you can substitute their values

for example instead of 3xy you can write 3*(-4)y

so that is the basic idea for this problem

after substituting, the new equation is 3*(-4)*2 +5

i plan on using order of operations, or PEMDAS

3*(-4)=(-12)

(-12)*2=(-24)

-24+5=-19

so the answer is -19

hope this helps!
