Answer:
$5.40
Step-by-step explanation:
To find the increase we need to consider our variables.
Current Rate = $4.50
Increase Percentage = 20% or 0.20
Now we can find the new rate by multiplying the Current Rate to the Increase Percentage and add it to the Current Rate again.
Total Price w/ Increase = ($4.50 x 0.20) + $4.50
Total Price w/ Increase = $0.90 + $4.50
Total Price w/ Increase = $5.40
Firstly, you need to combine like terms within that side of the equation.
Take -3x +9x and you’ll get 6x.
Next, combine like terms on the other side of the equation.
Take -5-1 and you’ll get -6
So far you should have:
6x+2=4x-6
Subtract 4x on each side!! Cancel 4x-4x! Solve 6x-4x!
Now you’ll get:
2x+2=-6
Subtract 2 on each side!!
Cancel out 2-2 and solve -6-2.
You should get:
2x=-8
Lastly, divide 2 on each side.
Cancel out 2/2 and solve 8/2.
Your final answer should be:
X = -4
(a) 50%
(b) 17%
Explanation:
(a)
No. of seniors = 54 + 46 = 100
Total No. = 66 + 34 + 54 + 46 = 200
% of seniors = 100/200 x 100% = 1/2 x 100% = 50%
(b)
No. of juniors that do not have a job = 34
Total No. = 66 + 34 + 54 + 46 = 200
% of juniors that do not have a job = 34/200 x 100% = 17/100 x 100% = 17%
