Whatever% of anything is just (whatever/100) * anything.
so 56% of 75 mates like it, how much is 56% of 75? well is just (56/100) * 75, namely 42.
and 80% of 60 relatives like it as well, how much is 80% of 60? well, is just (80/100) * 60, namely 48.
how many more? well, 48 - 42.
Answer:
Washing cars= 4 hours
Walking dogs= 10 hours
Step-by-step explanation:
You want to start by creating equations. So one thing we know is that he makes $9 an hour washing cars(x) and $8 walking dogs(y).
$9x+$8y=$116
The second Equation is based off of the hours worked. We know that he worked 6 hours more walking the dogs than he did washing cars, so we can take x(being the washing hours) and add 6 to it to equal y (the number of dog hours).
y=x+6
Now You plug what y equals into the first equation to solve for x.
9x+8(x+6)=116 Next distribute the 8 to each term.
9x+8(x)+8(6)=116
9x+8x+48=116 Add the like terms together (9x+8x)
17x+48=116 Subtract the 48 from both sides
-48 -48
17x=68 Now divide by 17 on both sides.
______
17 17
x=4 Finally we can take x and plug it back in to one of the equations in order to solve for y. I'm going to choose the second equation.
y=(4)+6
y=10
Given:
Taxable income: 7,500
Paid every two weeks or 26 weeks in a year
Based on 2007 Federal Income Tax Table for Single Taxpayer, Tim is under the tax range over $0 but not over $7,825. The tax is 10% of the amount over $0.
<span>1. Finds the tax rate for his income level =10 %
2. Enters the base amount = $7,500
3. Enters the amount of tax owed = $7,500 * 10% = $750
4. Divides by 26 = $750 / 26 = $28.85 tax withheld from biweekly wages.</span>
