Answer:

Cost Adult tickets = x
Cost Children's tickets = y
The total cost of ticket = C =
A family goes to an amusement park adult tickets cost $21 children under 10 years of age pay $15
C = $21 × x + $15 × y
C = 21x + 15y
The total cost of 4 adult tickets and 3 children's tickets is calculated as:
C = 21 × 4 + 15 × 3
C = 84 + 45
C = $129

Answer:
The markup rate is 51% on the cost
Step-by-step explanation:
Price of book = 7.99
Cost to the store = 5.29
The markup rate is a term used to figure what percentage is added on to the cost of the item to find its selling price.
If we subtract cost from the price we will know how much is added to actual cost: 7.99 - 5.29 = 2.7


Markup rate is 0.51*100 = 51%
