Creed's brother earns $12.00 per hour. The store offers him a raise -- A 5% increase per hour. After the raise, how much will Creed's brother make per hour?

Answers

Answer:

$12.60

Step-by-step explanation:

Creed's brother originally makes $12.00 an hour. A 5% raise means that:

$12.00 × 1.05 = $12.60

If you raise $12.00 by 5% then you have the formula
12x0.005=0.006
12+0.6=12.6
So after the raise Creeds brother will make $12.60/hour

Answer:

N= -5/8=0.625

Step-by-step explanation:

2.1      Solve  :    -8n-5 = 0  

Add  5  to both sides of the equation :  

                     -8n = 5

Multiply both sides of the equation by (-1) :  8n = -5

Divide both sides of the equation by 8:

                    n = -5/8 = -0.625

You need to work out how much $120 is as a percentage of $3000.

percentage = 12000 / 3000 = 4

= 4%

The work out 4% of $100 = $4.00

your friend evaluates the expression when m = 10. is your friend correct? Explain your reasoning.

3m - 6 = 3(10) - 6
= 3(4)
=12

PLS HELP ASAP!

Answers

Answer:

yes

Step-by-step explanation:

3 * 10 (m) = 30 so 30 - 6 = 24. 3(10) - 6 is basically the same thing just written different, so it equals 24 too. 3(4) just means 3 times 4 ,which equals 13. Hope that made sense lol

yes ,

3•10 = 30 - 6 = 24

now when you do 3(4) you get 12 and then subtract the 12 from the 24 and you get 12
