Sharon’s family budgeted $3000 for their vacation. Their budget consisted of $1850 for travel cost and $85 per day for hotel and other expenses. Which inequality will determine the amount of days Sharon’s family can stay on vacation?

• 1850 + 85x < 3000

• 1850 – 85x > 3000

• 1850 + 85x < 3000

• 1850 – 85x > 3000

Solve: -3x + 20 < 2x - 40
