Answer:

s + l = 6 = l = 6 - s. \\ 8s + 10l = 56 \\ 8s + 10(6 - s) = 56 \\  - 2s + 60 - 10s = 56 \\  - 2s =  - 4 \\ s =  \frac{ - 4}{2}  =  - 2. \\ s = small \: notebook  = 2. \\ l = large \: notebook = 6 - 2 = 4.

Step-by-step explanation:

S + L = 6 => L= 6-S

8S + 10L = 56

8S + 10(6-S) = 56

8S +60 -10S = 56

-2S = 56-60

-2S = -4

S = -4/-2

S = 2

=> S = small notebook = 2

L = large notebook = 6-2 = 4

Harry church borrowed 17,500.00 at 6.5% exact interest. He had to pay back a maturity value of 17,873.97 to pay off the loan. Wh
kirill [66]

Answer:the term of the loan is approximately 4 months

Step-by-step explanation:

The term of the loan means the period for which the loan was given.

We would apply the formula for simple interest which is expressed as

I = PRT/100

Where

P represents the principal

R represents interest rate

T represents time in years

I = interest after t years

From the information given

P = 17500

R = 6.5%

I = total amount paid - principal

I = 17,873.97 - 17,500.00 = 373.97

Therefore

373.97 = (17500 × 6.5 × T)/100

373.97 = 1137.5T

T = 373.97/1137.5

T = 0.32 years

Converting to months, it becomes

0.32 × 12 = 3.84

Approximately 4 months.
