Jill worked five hours less than three times the number of hours that Karen worked.  Which of the following equations represents the relationship between j, the number of hours that Jill worked and k, the number of hours that Karen worked?

• j = 3k - 5
• j = 1/3k - 5
• j = 3k + 5
• j = 1/3k + 5

Ingrid earns $200 each week in salary plus a 20% commission on her total sales.  If Ingrid wants to earn a total of $400 for the week, which of these equations could best represent this situation?

• 200 = 400 + .20x
• 200 = 400x + .20
• 400 = 200(.20) + x
• 400 = 200 + .20x

At the end of the football season, the Raccoons won 4 more than 2 times as many games as the Muskrats won.  Which of the following could be used to determine R, the number of games the Raccoons won in terms of m, the number of games the Muskrats won?

• R = 2(m-4)
• R = 2(m+4)
• R = 2m - 4
• R = 2m+4
