A.) $1.60 B.) $2.10 C.) $3.20 D.) $3.30 E.) $4.20
x = price of child's admission ticket
2x = price of adult's admission ticket {price of adult is twice the price of child} 2(2x) + 2x = 12.60 {2 adults and 2 children cost $12.60} 4x + 2x = 12.60 {multiplied 2 by 2x} 6x = 12.60 {combined like terms} x = $2.10 {divided each side by 6} price of child's admission ticket is B.) $2.10 Ask Algebra House Comments are closed.
