A family goes to an amusement park adult tickets cost $21 children under 10 years of age pay $15 write an algebraic expression for the total cost then find the total cost of 4 adult tickets and 3 children's tickets

$129

Step-by-step explanation:

Let us represent:

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

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
