Answer 1

• Becca's solution included all of the hours Javier worked on both weekends.

Explanation:

Javier needs to work at least 6 more hours. He will earn:

• 6*8 = $48

He has already got:

• $190 - $48 = $142

He worked:

• 142/8 = 18 hours (rounded)

Total he will have worked:

• 18 + 6 = 24 hours

Answer choices:

Becca's solution included all of the hours Javier worked on both weekends.

• TRUE

Javier worked a total of 23 hours on both weekends.

• FALSE. 23*$8 = $184 < $190

Javier earns $198 for 24 hours of work.

• FALSE. 24*8 = $192

Javier only needs to work one more hour to have enough money for his trip.

• FALSE. Becca says 6 more hours required.
