Question 4 (5 points)
The sum of two consecutive odd integers is 56.
What is the smaller number?

A.25
B.27
C.29
D.31

B

Step-by-step explanation:

note there is a difference of 2 between consecutive odd integers.

let the 2 integers be n and n + 2, then

n + n + 2 = 56, that is

2n + 2 = 56 ( subtract 2 from both sides )

2n = 54 ( divide both sides by 2 )

n = 27

Thus the smaller integer is 27 → B

The larger integer is n + 2 = 27 + 2 = 29

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
