140% = $34.30
1$ = 0.245
100% = 0.245 x 100 =$24.50
The cost of the sweater os $24.50
First 3/4: this is actually 0.75. but the percent means we have to divide it by 100:
0.0075
3/25 is actually 0.12 (because it's equal to 12/100: i multiplied both numbers by 4)
and if it's a percent, again we "move to "move the point" or in other words divide by a 100:
0.0012 (think of dividing by 10 as of moving the coma to the left and adding zeros if there is noone to move)
the last one is equal to 55/100 (multiplied both by 5), so 11/20 % is 0.0055
I hope this was clear, let me know if you have questions!

Step-by-step explanation:
<u>Step 1: Define equation</u>
4x - 1 = 7x - 16
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract 4x on both sides: -1 = 3x - 16
- Add 16 to both sides: 15 = 3x
- Divide 3 on both sides: 5 = x
- Rewrite: x = 5
<u>Step 3: Check</u>
<em>Plug in x into the original equation to verify it's a solution.</em>
- Substitute in <em>x</em>: 4(5) - 1 = 7(5) - 16
- Multiply: 20 - 1 = 35 - 16
- Subtract: 19 = 19
Here we see that 19 does indeed equal 19.
∴ x = 5 is a solution to the equation.
Answer:
$23,360
Step-by-step explanation:
Calculation to determine how much carol originally invested in the account
First step is to divide £23517.60 by 1.025
= (23,517.60)/(1+.025)
= (23,517.60)/1.025
=$22,944
Second step is to add back the $1,000 withdrew
=$22,944+$1,000
=$23,944
Now let calculate how much carol originally invested in the account
$23,944=1.025P
Divide both side by 1.025
P=$23,944/1.025
P=$23,360
Therefore the amount that carol originally invested in the account is $23,360
