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.
