1)

8.75 * 20 = 175

8 * 20 = 160

175 - 160 = 15

He'd make $15 more working at the amusement park.

2)

Semi-monthly means twice a month. So, her company is going from 2 to 4 pay periods.

3280 * 2 = 6560 (is what she makes per month)

6560/4 (because 4 weeks in a month) = 1640

OR (An alternative method.)

3280/2 = 1640

She'll be paid $1640 per week.

4)

105,000/12 (12 months in 1 year) = 8750 (He makes this per month)

8750 * 2 = 17500

He makes 17500 semi monthly

8750 /4 = 2187.5

2187.5 * 2 (because bi-weekly) = 4375

He makes 4375 bi-weekly

8750/4 = 2187.5

He makes 2187.5 every week

Dont forget to add the dollar signs. I didnt add them, but you need to. If you need me to add them I can.

the average sale of a house decreased from $317,000 in February 2008 to $160,000 in February 2013. What is the absolute change?
AURORKA [14]
The absolute change is expressed as a positive percentage here, which would be 49.53%. The relative change would be the same answer, only negative since the amount is going down. 

In order to find the percentage of change, you would subtract the new total from the previous total and then divide by the previous. 

\frac{Previous - New}{Previous}

\frac{317,000 - 160,000}{317,000}

\frac{157,000}{317,000}

49.53%
