Write and evaluate an expression to find the cost for 5 adults and 8 children.

Step-by-Step Solution

Answer

The expression and its value is: $5\times 45+8\times 25=425$.

Step 1. Given information.

Cost of ticket for an adult is 45.

Cost of ticket for a child is 25.

Step 2. Consider the variables.

If cost of one item is Rs x, then cost of n such items are $nx$.

Step 3. Write the expression.

Cost of tickets for $5$ such adults is $5\times 45$.

 

Cost of tickets for $8$ such children is width="43" height="20" style="max-width: none; vertical-align: -4px;" $8\times 25$.

 

So,

Total cost is given by the following expression,

$5\times 45+8\times 25$

Step 4. Simplify the expression.

The expression $5\times 45+8\times 25$ can be simplify in below.
