In 2006, a man has given a pay increase of 10%. In 2007, he suffered a pay out of 10%. Was he better off or worse off as compared to 2005

The man was worse off than in 2005

Step-by-step explanation:

Assume the man's salary in 2005 was $4,500.

In 2006 therefore, his salary goes to:

= 4,500 * (1 + 10%)

= $4,950

In 2007, this drops by 10%:

= 4,950 * ( 1 - 10%)

= $4,455

The man was worse off than in 2005 because the 10% reduction was based on the larger 2006 salary but the 10% increase was based on the smaller 2005 salary.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

third choice down

step-by-step explanation:

the first inequality is based on the number of adults and campers, and the second inequality is based on the cost of feeding both the adult and the camper.

we know that there is room for 525 people max.   it's ok to have less than 525, but it's not ok to have more than 525, so the inequality is less than or equal to.   the number combination of adults (x) and campers (y) cannot exceed this 525 max.   therefore:

x + y ≤ 525

now we talk about cost.   it costs $9 to feed one adult, so depending upon the number of adults you have (x) depends upon how much it will cost to feed that number of adults.   same with the campers, who cost $5 to feed.   the adults can be represented by 9x and the campers can be represented by 5y.   since the budget cannot exceed 1,200, the second inequality is:

9x + 5y ≤ 1200
