Solve for f.
Genrish500 [490]

Answer:

3

Step-by-step explanation:

4f-3 = 5f-6

First I would try to get the f's on one side and the other numbers on the other, to do this you woudl have to add 6 to both sides

4f -3 = 5f -6

  +6         +6

Making it into: 4f + 3 = 5f

Now to get the 4f on the other side we will have to subtract it from both sides

4f +3 = 5f

-4f         -4f

3= f  (Remember you do not have to put the 1, making 3 your answer)

The Supplemental Security Income (SSI) program, administered by the Social Security Administration (SSA), is the income source of last resort for thelow-income aged, blind, and disabled. As the nation's largest income-assistance program, it paid $38 billion in benefits in calendar year 2006 to roughly 7 million recipients per month. BecauseSSI is means tested, administering the program often requires month-to-month, recipient-by-recipient benefit recomputations. An increase in a recipient's income usually triggers a benefit recomputation. Or, an increase in the recipient's financial assets, which may render the recipient ineligible, would also prompt a recomputation. With this crush of ongoing recomputations, it is of little wonder that administrative simplification is a time-honored mantra for program administrators.

Serjik [45]

Answer:

42.8%

Step-by-step explanation:

Step one:

given data

A department store buys 100 shirts at a cost of ​$700

let us find the cost of 1 shirt

cost of 1 shirt= 700/100= $7 per shirt

The cost price per shirt = $7

We are given that the selling price = $10 per shirt

Step two:

The percent markup can be found as

percent markup= selling-cost price/cost price*100

percent markup= 10-7/10*100

percent markup= 3/7*100

percent markup= 0.428*100

percent markup= 42.8%
