Solving the inequality: $23>4n+11$ we get $n$

Step-by-step explanation:

We need to solve the inequality: $23>4n+11$

Solving the inequality:

Switch the sides and reverse the inequality:

$4n+11$

Subtract 11 from both sides

$4n+11-11$

$4n$

Divide both sides by 4

$n$

So, solving the inequality: $23>4n+11$ we get $n$

We know: The total number of tickets is 35. Another way of saying this is the number of adults plus the number of children equals 35. i.e.:

$Adults+Children=35$

Using the symbols provided we can write this is as:

$a+c=35$

We also know: The total money collected is $75. We know that $6 was collected for every adult or $6a$ and $1 for every child or $1c$ . i.e.:

$(SixDollars \times Adults)+(OneDollar \ times Children)= $70$

Using the symbols provided and adding it all up we can write this is as:

$6a+1c=70$

Equation 1: $a+c=35$
Equation 2: $6a+c=70$
