Linear Word Problems

While visiting Crimson Lake, Sally decided to go kayaking. The rangers charge $9 per hour in addition to a $30.00 deposit to rent the kayak. Write a linear equation to represent the total cost of the lake trip.

• y = 30x + 9

• y = 9x + 30

• y = -9x + 30

• y = 9x - 30

Alex bought a new truck for $25,000. According to the dealer, the truck will depreciate approximately $2,200 per year. Write a linear equation to represent the total cost of the truck.

• y = 25,000x + 2,200

• y = -25,000x + 2,200

• y = -2,200x + 25,000

• y = -2,200x - 25,000

Evan is going to the county fair this weekend. The admission to the fair is $10 and the cost per ride is $2. Write a linear equation to represent the total cost.

• y = 2x + 10

• y = -2x + 10

• y = 10x - 2

• y = 10x + 2

If you buy a car wash at the gas station for $6.00, the cost per gallon is $2.35. Then write a linear equation to represent your total cost of gas and car wash.

• y = 6x + 2.35

• y = 2.35x + 6

• y = -2.35x + 6

• y = 2.35x - 6

Francisco is saving money in an account. At the beginning of the year, he has $56 in savings and puts in another $4 per week. Write a linear equation to represent his total savings.

• s = 4w + 56

• s = 56w + 4

• s = -4w + 56

• s = 4w - 56
