Mrs. Gonzalez is going to rent a car for a business trip for one week. The total cost, C , for Top-Notch Car Rental is $150 plus $0.35 per mile, m . The total cost, C , for Fleetwood Car Rental is $200 and $0.10 per mile, m . Which company is less expensive for a 300-mile trip and by how much? Use 1 for Top-Notch Car Rental and 2 for Fleetwood Car Rental in the answer.(1 point)
The less expensive company is
by $
.
The less expensive company is
by $
.
Let's calculate the cost for each company for a 300-mile trip:
For Top-Notch Car Rental:
C1 = 150 + 0.35 * 300
C1 = 150 + 105
C1 = 255
For Fleetwood Car Rental:
C2 = 200 + 0.10 * 300
C2 = 200 + 30
C2 = 230
Comparing the costs:
C1 = $255 for Top-Notch Car Rental
C2 = $230 for Fleetwood Car Rental
Fleetwood Car Rental is less expensive for a 300-mile trip, by $25. The less expensive company is 2 by $25.
For Top-Notch Car Rental:
C1 = 150 + 0.35 * 300
C1 = 150 + 105
C1 = 255
For Fleetwood Car Rental:
C2 = 200 + 0.10 * 300
C2 = 200 + 30
C2 = 230
Comparing the costs:
C1 = $255 for Top-Notch Car Rental
C2 = $230 for Fleetwood Car Rental
Fleetwood Car Rental is less expensive for a 300-mile trip, by $25. The less expensive company is 2 by $25.
Akeem wants to have a lemonade stand at the community fair. It costs him $2 to make each cup of lemonade plus a $40 renter's fee for the stand. He sells the lemonade for $6 per cup. How many cups does Akeem have to sell to break even?
Let's denote:
Cost to make each cup of lemonade = $2
Renter's fee for the stand = $40
Selling price of each cup = $6
To break even, the total revenue must equal the total cost. The total cost equation is:
Total Cost = Cost to make each cup x Number of cups + Renter's fee
Total Cost = 2x + 40
The total revenue equation is:
Total Revenue = Selling price x Number of cups
Total Revenue = 6x
To break even, Total Revenue = Total Cost:
6x = 2x + 40
6x - 2x = 40
4x = 40
x = 40 / 4
x = 10
Akeem needs to sell 10 cups of lemonade to break even.
Cost to make each cup of lemonade = $2
Renter's fee for the stand = $40
Selling price of each cup = $6
To break even, the total revenue must equal the total cost. The total cost equation is:
Total Cost = Cost to make each cup x Number of cups + Renter's fee
Total Cost = 2x + 40
The total revenue equation is:
Total Revenue = Selling price x Number of cups
Total Revenue = 6x
To break even, Total Revenue = Total Cost:
6x = 2x + 40
6x - 2x = 40
4x = 40
x = 40 / 4
x = 10
Akeem needs to sell 10 cups of lemonade to break even.
The senior class at Hartford High School is planning their prom. They’ve narrowed the location down to two choices. The Regal Hotel charges, C , $500 for the ballroom rental fee and $75 per student, s , for the meal. The Greenhill Country Club charges, C , $1,000 for the ballroom rental fee and $65 per student, s , for the meal. Create a pair of linear equations that represent this real-world problem.(1 point)

Regal Hotel: C=1,000s+75; Greenhill Country Club: C=500s+65
Regal Hotel: C=75s+500; Greenhill Country Club: C=65s+1,000
Regal Hotel: C=500s+75; Greenhill Country Club: C=1,000s+65
Regal Hotel: C=75s+1,000; Greenhill Country Club: C=65s+500

Regal Hotel: C=1,000s+75; Greenhill Country Club: C=500s+65
Regal Hotel: C=75s+500; Greenhill Country Club: C=65s+1,000
Regal Hotel: C=500s+75; Greenhill Country Club: C=1,000s+65
Regal Hotel: C=75s+1,000; Greenhill Country Club: C=65s+500
The correct pair of linear equations that represent this real-world problem are:
Regal Hotel: C = 500 + 75s
Greenhill Country Club: C = 1000 + 65s
Regal Hotel: C = 500 + 75s
Greenhill Country Club: C = 1000 + 65s
