Writing Equations for Real-World Scenarios

Write an equation for:

A gym charges a $50 membership fee plus $20 per month.

• C = 50m + 20
• C = 50 - 20m
• C = 50 + 20m
• C = 20 + 50m

Write an equation for:

A taxi company charges $3 as a base fare and $1.50 per mile.

• F = 3 + 1.5 * m

• F= 3 + 1.5 * (m + 1)

• F = 1.5 + 3 * m

• F = 3 * m + 1.5

Write an equation for:

A water tank has 500 gallons of water and is being drained at a rate of 20 gallons per minute

• W= 500 - 10t

• W= 500 - 20t

• W= 20t

• W = 500 + 20t

Write an equation for:

A car rental company charges a fee of $40 and an additional $0.25 per mile driven

• T = 40 - 0.25m

• T = 40 + 0.50m

• T = 40 + m

• T = 40 + 0.25m

Write an equation for:

A store sells apples for $2 per pound, and there is an additional $5 delivery charge

• C= 5w + 2

• C= 2w - 5

• C = 5w - 2

• C= 2w + 5

Write an equation for:

A person earns $15 per hour and receives a $50 bonus at the end of each week

• E = 15h + 50

• E = 15h - 50

• E = 10h + 50

• E = 20h + 50

Write an equation for:

A rectangular pool is being filled at a constant rate of 30 gallons per minute.

The pool already contains 100 gallons of water.

• P = 100 + 30t

• P = 100 + 15t

• P = 100 - 30t

• P = 30t

Write an equation for:

A company produces notebooks, and the total cost of production includes a

fixed cost of $200 plus $5 per notebook.

• C = 200 + 5n
• C = 200 + n
• C = 5n
• C = 200 - 5n

Write an equation for:

The temperature of a liquid decreases by 4°F per minute. If the initial temperature is 80°F

• D = 80 - 4t

• D = 76 - 4t

• D = 80 - 2t

• D = 80 + 4t

Write an equation for:

A savings account has an initial balance of $1,000 and earns $50 in interest per year

• B = 1000 - 50t

• B = 1000 + 25t

• B = 1000 + 50t

• B = 500 + 50t
