Two companies offer Jane a sales position. Company A pays $3,000 per month plus $250 per car sold. Company B pays $2,500 per month plus $350 per car sold. Which equation could be used to determine the number of cars sold in a month, x, that would result in the same income from each company?

Bruce wants to have a laptop case shipped to his office. Company A charges a $10 shipping fee and $1 per pound. Company B charges a $12 shipping fee and $0.50 per pound. Write an equation to find the number of pounds, p, where the cost is the same.

• 10+p=12+0.5p

• 10+0.1p=12+0.5p

• 10p+1=12p+0.5

• 10p+0.1=12p+0.5

Ryan and Sarah collect baseball cards. Ryan has 150 baseball cards and collects 10 per week. Sarah has 200 baseball cards and collects 5 per week. Write an equation to determine the number of weeks, w, it would take for Ryan and Sarah to have the same amount.

• 150w+10=200w+5

• 150w-10=200w-5

• 150-10w=200-5w

• 150+10w=200+5w

• x=-5

• x=5

• x=3

• x=-3

• x=-6

• x=6

• x=-3

• x=3
