Answer:
A. 27.50 = 5.50 + 2.75h
B. 8 hours
C. 9 hours
Step-by-step explanation:
Total spent = $27.50
Base fee = $5.50
Hourly rate = $2.75
A. Create an equation that can be used to determine how many additional hours, ℎ, Rose parked her car in the garage
Total cost = fixed cost + variable cost
27.50 = 5.50 + 2.75h
B: Solve the equation to determine the number of additional hours, ℎ, Rose parked her car in the garage.
27.50 = 5.50 + 2.75h
Subtract 5.50 from both sides
27.50 - 5.50 = 5.50 - 5.50 + 2.75h
22 = 2.75h
Divide both sides by 2.75
h = 22/2.75
= 8
h = 8 hours
C: What is the total number of hours that Rose parked her car in the garage
Total number of hours = first hour + additional hours
= 1 + 8
= 9 hours
One way is just to recognize that
2.88=12 cookies
konw that
12/6=2
so divide both sides by 6
0.48=2 cookies
2 cookies is 48 cents
ratio and proportaion way
cost:cookies=2.88:12
cost of 2 cookies is x
2.88/12=x/2
times both sides by 12
2.88=6x
divide both sides by 6
0.48=x
the cost is 2 cookies is $0.48 or 48 cents
Answer:
Option B. 5 hours
Step-by-step explanation:
The tennis club charges monthly fees = $50.00
and per hour charges of court time = $10.00
Lets assume you play number of hours in a month = x hr
So, per hour charges would be = $10x
Total payment = monthly charges + charges of played hours
$100.00 = $50.00 + 10x
10x = 100 - 50
10x = 50
x = 5
Option B. You used 5 hours court time.

Answer:
18 small dogs
Step-by-step explanation:
Given the ratio of small dogs to all dogs was 3:7
Total dogs that are there = 42 dogs
Number of small dogs there = ratio of small/ratio of all dogs * Total dogs
Number of small dogs there = 3/7 * 42
Number of small dogs there = 3 * 6
Number of small dogs there = 18
Hence there are 18 small dogs there
