2) A concert ticket costs [tex]p[/tex] dollars for an adult and [tex]q[/tex] dollars for a child. Find an expression that represents the total cost for 4 adults and 6 children.
3) Two apartments have numbers that are consecutive integers. The sum of the numbers is 59. What are the two apartment numbers?
Answer (3)
y:10;
4p+6q;
x +( x+ 1) = 59 => 2x = 58 => x = 29 => 29 and 30;
10y
4p+6q
x+x+1=59
2x=58
x=29
29+1=30
the 2 numbers are 29 and 30
The expression for the number of $10 bills is 10 y . The total cost for 4 adults and 6 children is represented by 4 p + 6 q . The two consecutive apartment numbers that add up to 59 are 29 and 30.
