Answer: 1 = 2 = 3 = 90
4 = 113
5 = 6 = 180 - 113 = 67
8 = 180 - (90+67) = 180 - 157 = 23
7 = 9 = 180 -23 = 157

Step-by-step explanation:

Sam took his family to the zoo. An adult's ticket is two times the cost of a child's ticket. The total cost for two adults' tickets and three children's tickets was $28. How much do the tickets cost?

Answers

Hello,

Let x the cost of a child's ticket
2x is the cost of an adult's ticket

2*(2x)+3x=28
==>4x+3x=28
==>7x=28
==>x=4

2x=2*4=8

Proof:
2 adult's tickets: 2*8=16
3 child's tickets: 3*4=12
and 16+12=28.

Adult's ticket cost is 8
Child's ticket cost is 4

C=children's ticket. 2c=adult ticket. 2c+2c+c+c+c=$28. Add the c's: 4c+3c=$28. Keep adding/ 7c=$28. Divide by 7: c=$4. A children's ticket is $4 an adult ticket is $8 :)
