Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 …
Profit and Loss

Based on the federal tax chart what are the taxes owed in the following situation Taxable income $45,000
Sara has an annual income of $70,000. Using the tax table If taxable But not income The tax is: over-- is over-- $0 $16,750 10% of the amount over $0 $16,750 $68,000 $1,675.00 plus 15% of the amount over 16,750 $9,362.50 plus 25% of the amount $68,000 $137,300 over 68,000 $26,687.50 plus 28% of the amount $137,300 $209,250 over 137,300 $46,833.50 plus 33% of the amount $209,250 $373,650 over 209,250 $101,085.50 plus 35% of the $373,650 no limit amount over 373,650 1. Calculate how much money she pays in taxes. 2. Calculate how much she saves in taxes by putting $150/month into this account (which means the money is deducted from income before taxes are calculated). 3. If Sara was the same employee from the previous question, is the flexible spending plan worth it for her? Why or why not?
