Answer:
Part A: 25% of 50 = 12.5
Part B: 25% of 60 = 15
Part C: 50% of 60 = 30
Part D: 75% of 60 = 45
Part E: 75% of 30 = 22.5
Part F: 100% of 22.5 = 22.5
Part G: 10% of 22.5 = 2.25
Part H: 50% of 45.7 = 22.85
Step-by-step explanation:
To find - Do you know the answer to
Part A: 25% of 50 =
Part B: 25% of 60 =
Part C: 50% of 60 =
Part D: 75% of 60 =
Part E: 75% of 30 =
Part F: 100% of 22.5 =
Part G: 10% of 22.5 =
Part H: 50% of 45.7 =
Proof -
Part A :
25% of 50 = 
= 
= 12.5
⇒25% of 50 = 12.5
Part B :
25% of 60 = 
= 
= 15
⇒25% of 60 = 15
Part C :
50% of 60 = 
= 
= 30
⇒50% of 60 = 30
Part D :
75% of 60 = 
= 
= 45
⇒75% of 60 = 45
Part E :
75% of 30 = 
= 
= 22.5
⇒75% of 30 = 22.5
Part F :
100% of 22.5 = 
= 22.5
⇒ 100% of 22.5 = 22.5
Part G :
10% of 22.5 = 
= 2.25
⇒ 10% of 22.5 = 2.25
Part H :
50% of 45.7 = 
= 
= 22.85
⇒50% of 45.7 = 22.85
Let the number of ride tickets = x tickets.
And the total cost is given by y.
Fair charges $1.25 per ticket for the rides.
Johnny bought = 25 tickets.
Therefore, cost of 25 tickets @ $1.25 per ticket = 25 × 1.25 = $31.25
Total amount spent at the fair = $43.75.
Fair admission charge = Total amount spent - Cost of 25 tickets = 43.75 - 31.25 =$12.50.
Therefore, total cost of the fair = Fix fair admission charge + total cost of x number of tickets @1.25 each.
y = 12.50 + 1.25x.
Therefore, y = 12.50 + 1.25x is the linear equation that can be used to determine the cost for anyone who only pays for x ride tickets and $ 12.50 fair admission.
