The sum of two numbers is 20 and their difference is 12.

4 and 16

Step-by-step explanation:

First, let's find first term using sum formula:

We know that d or common difference is 12 and only sum of two terms so n = 2.

Since sum of two numbers equal 20.

From above, subtract both sides by 12, solving for a1.

Therefore our first number is 4.

Finding next number, create an equation:-

Another number is 16

So 4 and 16 has 12 as difference because 4+12=16 and 16-12 = 4

step-by-step explanation:

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
