A certain zoo charges twice as much for an adult admission ticket as for a child's admission ticket. If the total admission price for the family of two adults and two children is $12.60, what is the price of a child's ticket?

A.) $1.60

B.) $2.10

C.) $3.20

D.) $3.30

E.) $4.20

A.) $1.60

B.) $2.10

C.) $3.20

D.) $3.30

E.) $4.20

x = cost of child's ticket

2x = cost of adult's ticket {adult admission is twice as much as child's}

2(x) + 2(2x) = 12.60 {total price for 2 adults and 2 children is 12.60}

2x + 4x = 12.60 {multiplied through on left side}

6x = 12.60 {combined like terms on left side}

x = 2.10 {divided both sides by 6}

child's ticket price = $2.10

**B.) $2.10**
