An example of consecutive odd integers is 23, 25, 27, and 29. Find four consecutive odd integers with a sum of 160. Show your wo
Andrew [12]
Step1: Define an odd integer.
Define the first odd integer as (2n + 1), for n = 0,1,2, ...,
Note that n is an integer that takes values 0,1,2, and so no.

Step 2: Create four consecutive odd integers.
Multiplying n by 2 guarantees that 2n will be zero or an even number.
Therefore (2n + 1) is guaranteed to be an odd number.
By adding 2 to the odd integer (2n+1), the next number (2n+3) will also be an odd integer.

Let the four consecutive odd integers be
2n+1, 2n +3, 2n +5, 2n +7 

Step 3: require that the four consecutive integers sum to 160.
Because the sum of the four consecutive odd integers is 160, therefore
2n+1 + 2n+3 + 2n+5 + 2n +7 = 160
8n + 16 = 160
8n = 144
n = 18

Because 2n = 36, the four consecutive odd integers are 37, 39, 41, 43.

Answer: 37,39,41,43

Sales tax rate for the above sweater is charged at the rate of 8%

Step-by-step explanation:

Sweater’s cost initially- 28$

Cost of Sweater after 30.24$

Sales tax rate deducted?

Analysing the above-provided details we conclude that an increase in the cost was probably due to the addition of sale tax.

Sales tax charged= Cost of the sweater after charging- initial cost

= 30.24$-28$

=2.24$

Percentage of sales tax charged= (sales tax charged/initial cost) *100

Substituting the values of the sales tax and initial cost in the above-provided equation-

= (2.24/28) *100

=8%

Hence the Sales tax charged at the sweater was 8%
