Question

Tickets for 2 adults and 4 children at a theme park cost £152.

Answer 1

Answer:

The price of adult ticket is £38.

Step-by-step explanation:

First, you have to form equations in terms of a (adult) and c (child) :

$2a + 4c = 152 - - - (1)$

$a = 2c - - - (2)$

Next, you have to solve these equations by substitution :

$(2)→(1)$

$2(2c) + 4c = 152$

$8c = 152$

$c = 152 \div 8$

$c = 19$

$substitute \: c = 19 \: into \: (2)$

$a = 2 \times 19$

$a = 38$
