Real World Two Step Equation

A car rental company charges $50 per day plus $0.25 per mile driven. If a customer rents a car for x days and drives y miles, how much does the customer pay in total?

• Total cost = (50 * x) + (0.25 * y)

• Total cost = (50 * x) - (0.25 * y)

• Total cost = (50 + x) + (0.25 * y)

• Total cost = (50 * x) + (0.25 / y)

3. A recipe calls for 2 cups of flour to make 12 cookies. If you want to make x cookies, how many cups of flour do you need?

• x = (2 * number of cookies) / 24

• x = (2 * number of cookies) / 6

• x = (2 * number of cookies) / 10

• x = (2 * number of cookies) / 12

A taxi charges $3.50 for the first mile and $1.25 for each additional mile. If a customer takes a taxi for x miles, how much does the customer pay in total?

• Total cost = $3.50 + $1.25 * (x - 1)

• Total cost = $3.50 + $1.25 * (x + 1)

• Total cost = $3.50 - $1.25 * (x - 1)

• Total cost = $3.50 * (x - 1) + $1.25

A gym membership costs $50 per month plus a one-time enrollment fee of $100. If a customer signs up for x months, how much does the customer pay in total?

• $150x

• $50 + $100x

• $50x - $100

• $100 + $50x

A company offers a base salary of $2000 per month plus a commission of 5% on sales. If an employee makes x dollars in sales, how much does the employee earn in total?

• Total earnings = $2000 - 0.05x

• Total earnings = $2000 * 0.05x

• Total earnings = $2000 + 0.05x

• Total earnings = $2000 / 0.05x

4. A phone plan charges a monthly fee of $20 plus $0.10 per minute for calls. If a customer makes x minutes of calls in a month, how much does the customer pay in total?

• $15 + $0.15x

• $10 + $0.20x

• $20 + $0.10x

• $25 + $0.05x

For a field trip 4 students rode in cars and the rest filled nine buses. How many students were in each bus if 472 students were on the trip?

• 4x=472

• 9x=472

• 4+9x=472

• 4+x=472

After paying $5.12 for a salad, Kamauri has $27.10. How much money did he have before buying the salad?

• n + $5.12 = $27.10

• n - $5.12 = $27.10

• n - $5.12 = -$27.10

• $5.12 - n = $27.10

2x + 1 = 6

What would the first step be in solving this equation?
