Mr. and mrs. jones wanted to plan a fun day with their two children. an adult ticket to the local amusement park is $20. a child’s ticket is 40 percent less than the adult ticket. what is the total amount for a family of four to enter the park?

It would cost $56

Step-by-step explanation:

2 adults = 20 + 20 = 40

20 * 0.40 = 8

2 children = 8 + 8 = 16

16 + 40 = 56

$64

Step-by-step explanation:

Adult ticket = $20 (base cost, which we take is 100% of the total)

100% - 40% = 60%

Child ticket = $20 x 60% = $12

2 Adult + 2 Child Tickets = $20 + $20 + $12 + $12 = $64

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

a
