The admission fee at an amusement park is 1.5 dollars for children and 4 dollars for adults. On a certain day, 350 people entered the park, and the admission fees collected totaled 1000 dollars. How many children and how many adults were admitted?

160 children and 190 adults were admitted.

Step-by-step explanation:

Let x represent the number of children that were admitted on that day.

Let y represent the number of adults that were admitted on that day.

On a certain day, 350 people entered the park. It means that

x + y = 350

The admission fee at an amusement park is 1.5 dollars for children and 4 dollars for adults. The admission fees collected on that day totaled 1000 dollars. It means that

1.5x + 4y = 1000- - - - - - - - - - -1

Substituting x = 350 - y into equation 1, it becomes

1.5(350 - y) + 4y = 1000

525 - 1.5y + 4y = 1000

- 1.5y + 4y = 1000 - 525

2.5y = 475

y = 475/2.5

y = 190

x = 350 - y = 350 - 190

x = 160

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
