Answer:
-9, 15
Step-by-step explanation:
Subtract 7 and multiply by 4
1/4 |2x-6| +7 = 13
1/4 |2x -6| = 6
|2x -6| = 24
2x -6 = ± 24
2x = 6 ±24
x = 3 ±12
x = -9, 15
_____
For graphing purposes, it is often convenient to rewrite the equation so the solutions are where the function is zero. Here, we can do that by subtracting 13 from the equation.
(1/4 |2x -6| +7) -13 = 0
Answer:
60%
Step-by-step explanation:
Given data
we are told that 24 canisters cost $60
hence the cost per canister = 60/24= $2.5
The selling price per canister= $4
%mark up = selling price-cost price/cost price *100
Substitute
%mark up = 4-2.5/2.5 *100
%mark up = 1.5
/2.5 *100
%mark up = 0.6 *100
%mark up = 60%
Hence the percent mark up is 60%
Answer:
First, converting R percent to r a decimal
r = R/100 = 5.5%/100 = 0.055 per year.
Putting time into years for simplicity,
6 months / 12 months/year = 0.5 years.
Solving our equation:
A = 200(1 + (0.055 × 0.5)) = 205.5
A = $205.50
