One number is seven more than three times another number. If the sum of the numbers is 15, find the numbers.

2 and 13

Step-by-step explanation:

We can use systems of equations here to find both the numbers. Let's assume one of the numbers is and the other is .

We know that these numbers add up to 15, so .

We also know that one of these numbers is 7 more than 3 times the other, so .

We can now substitute the equation into .

Combine like terms:

Subtract 7 from both sides:

Divide both sides by 4:

.

Now that we know the value of , we can substitute it inside an equation to find . Let's substitute it inside .

So the two numbers are 2 and 13.

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
