Final answer:
The number of children and adults using a public swimming pool can be determined by solving a system of linear equations, representing the total number of people (C + A = 486) and the total receipts ((1.58 * C) + (2.25 * A) = 930.76). By expressing children (C) in terms of adults (A), and substituting into the second equation, the values can be calculated.
Step-by-step explanation:
To determine the number of children and adults using a public swimming pool, given a total of 486 people and receipts of $930.76 with ticket prices of $1.58 for children and $2.25 for adults, we can use a system of linear equations. Let's define the number of children as C and the number of adults as A.
The two equations to represent the situation are:
- C + A = 486 (represents the total number of people)
- (1.58 * C) + (2.25 * A) = 930.76 (represents the total amount of money collected)
Step by step, we solve this system as follows:
- Use the first equation to express C in terms of A: C = 486 - A.
- Substitute C in the second equation: 1.58(486 - A) + 2.25A = 930.76.
- Multiply and simplify the equation to find A.
- Once A is found, use the value of A to find C using the first equation.
Without providing the actual calculated numbers (which you should do by yourself to practice algebra), this step-by-step explanation should guide you through solving for the number of children and adults.
